Two new polls of Iowa Republicans show Dr. Ben Carson has taken the lead from Donald Trump. Selzer & Co’s latest survey for the Des Moines Register and Bloomberg Politics shows Carson is the first choice of 28 percent of likely Republican caucus-goers, followed by Trump at 19 percent, U.S. Senator Ted Cruz (10 percent), U.S. Senator Marco Rubio (9 percent), former Florida Governor Jeb Bush and U.S. Senator Rand Paul (5 percent each), business executive Carly Fiorina (4 percent), former Arkansas Governor Mike Huckabee (3 percent), Louisiana Governor Bobby Jindal, Ohio Governor John Kasich, and former Senator Rick Santorum (2 percent each), New Jersey Governor Chris Christie (1 percent), and the rest of the field below 1 percent.

Similarly, Quinnipiac’s latest poll of likely Republican caucus-goers found Carson ahead of Trump by 28 percent to 20 percent, followed by Rubio (13 percent), Cruz (10 percent), Paul (6 percent), Fiorina and Bush (5 percent each), and no one else above 3 percent.

Carson is the best-liked candidate among those likely to participate in the Iowa GOP caucuses. Both the Selzer and Quinnipiac surveys found that 84 percent of respondents view him favorably. I’ve posted more excerpts from the poll write-ups after the jump.

Carson is crushing the competition among social conservatives, an important bloc that tends to break late in Iowa caucus campaigns, as Bleeding Heartland guest author fladem discussed here. He has invested heavily in direct mail and leaving copies of his paperback books on Iowa Republican doorsteps, while generally escaping scrutiny from his competitors.

At some point, other candidates who are appealing primarily to the religious right must recognize that their path to relevance in Iowa runs through Carson. Only 22 percent of Selzer poll respondents said their minds are made up; 78 percent could change their minds. I’m curious to see when 2008 winner Huckabee, 2012 winner Santorum, and/or Jindal will start making a case against the surgeon. To be stuck in the cellar after spending substantially more time in Iowa than Carson must be so frustrating.

Cruz may also need to give Iowans a reason not to support Carson. Perhaps some of his Christian conservative surrogates could take on that role. “Opinion leaders” backing Cruz include numerous evangelical clergy, talk radio host Steve Deace, and Dick and Betty Odgaard, the self-styled martyrs to marriage equality in Iowa.

UPDATE: I should have mentioned that Nick Ryan, who led the 501(c)4 group American Future Fund for several election cycles and headed the pro-Santorum super-PAC during the 2012 primaries, signed on earlier this year to lead a super-PAC supporting Huckabee. It might make more sense for that group to go after Carson than for Huckabee to do so directly. Still, the next GOP debate on October 28 would be a good opportunity for rivals to score points against the new Iowa front-runner.

Eleven GOP candidates are just starting the “varsity” debate on CNN now. I will update this post later with some clips and thoughts. This thread is for any comments about today’s debates or the presidential race in general.

I only caught part of the first debate, featuring four candidates who didn’t make the cut for prime time. But from what I saw of Lindsey Graham, Bobby Jindal, George Pataki, and Rick Santorum, I think former Libertarian candidate for Iowa secretary of state Jake Porter said it best: “It is like the comments section decided to run for President and is now debating on live TV.”

10 PM UPDATE: My immediate reaction is that Carly Fiorina had an excellent debate, except for her closing statement, which sounded too memorized and rehearsed. Some of what she said was false (for instance, her comments about the Planned Parenthood videos), but that will go over well with the GOP base viewers. She did exceptionally well at modulating her voice, so that she sounded forceful and knowledgeable but also calm and steady. Everyone expected her to have a good comeback against Donald Trump, and she did, but it wasn’t just that answer. She was able to articulate a credible-sounding response on most of the topics that came up. She also produced the “most-tweeted moments” during the debate.

Trump made little sense, as usual. He started out as a caricature of himself, bragging about how many billions of dollars he has made. He claimed to have fought hard against going to war in Iraq–will be interesting to see whether there is any evidence to back that up. I don’t remember Trump speaking out against the war. I was surprised to hear Trump argue that vaccines can cause autism if kids get too many close together. I would guess that won’t hurt him.

Ben Carson gained the most from the first debate, and I don’t think he lost any ground tonight. That’s bad news for Mike Huckabee and Ted Cruz, who are fighting hard for evangelical support but didn’t seem to make their mark in this debate.

Chris Christie had more strong moments tonight than in last month’s Fox debate. I think he will gain more than John Kasich, who is essentially fighting for the same Republican moderate voters.

Rand Paul didn’t make a big impression during most of the debate, but he did well during the discussion on drug policy, especially calling out Jeb Bush for wanting to lock up poor people for using the same drugs Jeb used as a young man.

Bush had the second-most speaking time after Trump, and he landed some decent punches, but overall, I question whether he gained many supporters. He didn’t do a terrible job, though it was laughable when he suggested putting Margaret Thatcher on the ten-dollar bill.

Scott Walker had the least speaking time, according to NPR, and didn’t create any memorable moment. This event won’t reverse his falling poll numbers.

I saw some people saying on social media that Marco Rubio had a good night. The only comment that stood out for me was his saying his grandfather taught him about the American Dream in Spanish. Otherwise, I am still baffled by what so many people see in Rubio.

It was a huge mistake for the Democratic National Committee not to schedule any debates between the first two Republican clashes. The contrast in the level of discourse would have been tremendous for the Democratic candidates.  

Outsiders reign supreme in Quinnipiac’s latest poll of “likely Republican Caucus participants” in Iowa. Click here for the polling memo and full results. After the jump I’ve posted a couple of tables from the release.

Donald Trump is the first choice of 27 percent of participants, with Ben Carson not far behind at 21 percent. Carson leads among self-identified “born-again evangelicals” in the respondent pool. Among all respondents, Ted Cruz places a distant third at 9 percent, followed by Jeb Bush (6 percent), Carly Fiorina, John Kasich, and Marco Rubio (5 percent each), Rand Paul, Mike Huckabee, and don’t know/not answer (4 percent each).

Just a couple of months ago, Scott Walker led Quinnipiac’s Iowa poll with 18 percent support. The latest survey puts him in tenth place with 3 percent.

Adding today’s data to findings from other recent surveys, I believe we can answer the question Bleeding Heartland posed about the Wisconsin governor in March. Despite getting a decent head start here, Walker is looking like the second coming of Tim Pawlenty.

Any comments about the Republican presidential race are welcome in this thread.

Happy Labor Day weekend to the Bleeding Heartland community! This is an open thread: all topics welcome. Click here for a brief history of the holiday.

For those wanting to enjoy the outdoors during the unofficial last weekend of summer, you may find some inspiration in the Iowa Department of Natural Resources’ list of fourteen “incredible hikes in our state parks and forests,” here and here. I’m embarrassed by how few of those parks I have visited, but I can highly recommend the walking trails at the Ledges and Dolliver Memorial State Parks.

Three more polling firms have released new Iowa caucus surveys since last weekend’s Selzer poll for the Des Moines Register and Bloomberg news. Highlights are after the jump. All recent polls put Donald Trump and Ben Carson well ahead of the rest of the Republican field in Iowa. Bernie Sanders has clearly gained some ground on Hillary Clinton, but other polls have found a larger lead for the Democratic front-runner here than Selzer did.

Eric Boehlert was quick to criticize the media for giving Selzer’s poll of Iowa Democrats such big play last weekend, even though it looks like an “outlier” in his view. I take his point, but the last time I said a Selzer poll appeared to be an outlier, I had to eat my words.

Before I get to the polls below, here’s one for the “campaigns don’t matter” crowd, who believe economic conditions largely decide presidential elections. The Moody’s Analytics model “now predicts a Democratic electoral landslide in the 2016 presidential vote,” with 326 electoral votes for the Democratic nominee and 212 to the Republican. Click through for more information on the Moody’s methodology.

Selzer & Co’s new survey of Iowa Republicans for the Des Moines Register and Bloomberg News gives GOP strategists plenty to worry about.

The top three “outsider” candidates (Donald Trump, Ben Carson, and Ted Cruz) are the first choice for 49 percent of respondents. The top three “establishment” candidates (Scott Walker, Jeb Bush, and Marco Rubio) are the first choice for only 20 percent.

The survey also indicates that several candidates considered heavyweight contenders are yesterday’s news for likely GOP caucus-goers. The 2008 caucus winner Mike Huckabee is sitting at 4 percent, tied with Rand Paul, who had been expected to inherit much of his father’s support from the last election campaign. The 2012 winner Rick Santorum is at 1 percent.

The Des Moines Register’s Jennifer Jacobs wrote up the key findings here, with input from Jason Noble. My first thoughts about the numbers are after the jump.

Public Policy Polling released its latest Iowa caucus numbers yesterday. As other recent surveys of Iowa Democrats have shown, Hillary Clinton still leads by a considerable margin, but her lead has shrunk since the spring, as Iowans have learned more about other contenders. PPP now has Clinton at 52 percent support among “usual Democratic primary voters,” while Bernie Sanders has 25 percent, Martin O’Malley 7 percent, Jim Webb 3 percent, and Lincoln Chafee 1 percent.

On the GOP side, Donald Trump leads among “usual Republican primary voters” with 19 percent, followed by Ben Carson and Scott Walker (12 percent each), Jeb Bush (11 percent), Carly Fiorina (10 percent), Ted Cruz (9 percent), Mike Huckabee and Marco Rubio (6 percent each), John Kasich and Rand Paul (3 percent each), Bobby Jindal, Rick Perry, and Rick Santorum (2 percent each), Chris Christie (1 percent), and Jim Gilmore, Lindsey Graham, and George Pataki (less than 1 percent).

Dropping to 3 percent earned Paul the “biggest loser” title from Public Policy Polling’s Tom Jensen and was the only topline result that shocked me. Things got way more interesting in the cross-tabs. I enclose below the five findings that struck me most.

As a bonus, I added at the end of this post completely unsurprising numbers from PPP’s survey of registered Iowa voters: Governor Terry Branstad is underwater with 42 percent approval and 47 percent disapproval. Last month’s high-profile line-item vetoes are even less popular.

The Republican presidential candidates debated for the first time today in Cleveland. First, the seven contenders who didn’t make the cut for the prime-time event participated in a “happy hour” debate (some commentators called it the “junior varsity” or “kids’ table” debate). I missed the beginning of that event, but from what I saw, Carly Fiorina and Bobby Jindal stood out. Jindal’s closing statement seemed the strongest to me (if I try to imagine how a conservative would receive the messages). Rick Santorum and Rick Perry had some good moments. Lindsey Graham seemed to give rehearsed answers that weren’t always relevant to the question. George Pataki was memorable only for being the sole pro-choice candidate in a field of seventeen. Jim Gilmore failed to provide any good reason for him to be there.

The Fox News panel seemed determined to go after Donald Trump. He didn’t have a convincing story for why he has changed his mind on issues like abortion rights and single-payer health care. His answer to the question about his corporate bankruptcies struck me as extremely weak and weaselly. On the plus side, he deflected a question about his disgusting sexist remarks by beating his chest about political correctness. He also got the most speaking time–twice as much as Rand Paul, who had the least time to speak.

Paul scored a hit by calling attention to the fact that Trump won’t rule out running for president as an independent. Paul also slammed Chris Christie for giving President Barack Obama “a big hug.” Although Christie handled that exchange well, I am skeptical he can overcome his high negatives with GOP base voters. I felt Paul got the better of Christie during their heated exchange over warrantless wiretapping and the Fourth Amendment. UPDATE: As of Friday morning, a “Vine” of Paul rolling his eyes while Christie talked had more than 4 million loops.

John Kasich staked out a moderate-conservative niche that the pundits loved. I’m not convinced he can become a real contender for the nomination, but he certainly has a story to tell.

I don’t understand the hype about Marco Rubio. He doesn’t impress me at all.

Jeb Bush didn’t speak fluidly or forcefully. I read that he didn’t do “live” debate prep with his staff. If that’s true, it was a mistake. Scott Walker was also underwhelming, and I expected more of a splash from Ted Cruz, though maybe they had some better moments in the parts I missed. In contrast, Mike Huckabee is an excellent communicator. Ben Carson didn’t seem to get questions that allowed him to distinguish himself. His tax reform proposal is based on what the Bible says about tithing.

Factcheck.org exposed some false statements from the “happy hour” and the prime time debate.

Any comments about the debates or the Republican presidential race are welcome in this thread.

UPDATE: Trump’s further insults to Megyn Kelly of Fox News got him uninvited from this weekend’s Red State forum, prompting a typically outrageous response from the Trump campaign. Meanwhile, sexist tweets about Kelly have exploded since the debate. I believe women watching the debate would have felt deeply alienated by how many in the audience approved of Trump’s answer to the question about his sexism.  

Governor Terry Branstad will appeal to television networks and the Republican National Committee leadership to allow more GOP presidential candidates to participate in debates, Radio Iowa’s reported today. It’s not every day I agree with Iowa’s governor, especially on a matter of political fairness, but Branstad got this one right.  

The August straw poll is traditionally the most-watched “cattle call” before the Iowa Republican caucuses and an important state GOP fundraiser.

Responding to criticism of past straw polls, the Republican Party of Iowa revamped this year’s plans, hoping to encourage broad participation. However, signs point to most of the top-tier presidential candidates opting out.

What’s on your mind this weekend, Bleeding Heartland readers? This is an open thread: all topics welcome.

Confession: I didn’t watch any speeches at the Iowa Agriculture Summit. I followed some through many people’s tweets and caught up on the rest through Pat Rynard’s liveblog at Iowa Starting Line. As expected, given the background of moderator and organizer Bruce Rastetter, the event was no non-partisan issue forum. The audience for this “informercial for agribusiness” was overwhelmingly Republican, and some Democrats who wanted to attend were turned away at the door.

I enjoyed one person’s comment on the “twilight zone trifecta”: watching a parade of Republicans profess their love for government mandates (the Renewable Fuels Standard), subsidies, and science. The same person observed that the summit was “a textbook course on cognitive dissonance as hatred for @EPA clashes w/ begging them for #RFS mandates.” Speaking of cognitive dissonance, how about former Arkansas Governor Mike Huckbee (an ordained Christian minister) criticizing immigrants who come to this country for free “goodies” and “a bowl of food.”

Former Iowa Secretary of Agriculture and Lieutenant Governor Patty Judge was the only Democrat to accept Rastetter’s invitation to speak at the event. Rynard saw that as a “missed opportunity” for other Democrats, but I believe there is little upside to validating Rastetter as some kind of neutral authority or referee. He isn’t, and he never will be. Judge was reportedly well-received, probably because she’s not running for any political office again.

Some important problems facing Iowa farmers didn’t come up much, if at all, in Rastetter’s Q&A format. Soil erosion is not only a major factor in water pollution but also a costly trend for the agricultural sector. Rick Cruse of Iowa State University has researched the economic costs of soil loss and the associated impact on crop yields. Iowans who wanted to learn about those issues were better off attending a different event in Des Moines on March 7: the Raccoon River Watershed Association’s ninth annual Iowa Water Quality conference. Excerpts from Ben Rodgers’ report for the Des Moines Register are after the jump.

Final related note: on Friday, Sena Christian profiled four women farmers who are “stepping up to sustain the land.” One of them is LaVon Griffieon of Ankeny, a superstar whom I’m proud to call a friend. Click through to read Christian’s post at Civil Eats.

What’s on your mind this weekend, Bleeding Heartland readers? Newt Gingrich is probably wondering who’s going to pay for him to fly around the country on private jets. His presidential campaign can’t afford the expense anymore, and his former gravy train 527 group American Solutions went belly up last month.
