President Barack Obama rallied supporters in Davenport this morning, and his Republican challenger Mitt Romney is scheduled to campaign in Cedar Rapids tonight. After the jump I’ve enclosed highlights from Obama’s event and other links about the presidential campaign in Iowa. I will update this post later with highlights from the Romney rally.

Bleeding Heartland is updating absentee ballot totals statewide and in the four Congressional districts here every weekday. As of October 23, more than 540,000 Iowans had requested absentee ballots. With today’s early voting included, the statewide ballot requests will surpass the total Iowa early vote in 2008.  

Preliminary results from today’s Texas primary indicate that Mitt Romney now has enough delegates to win the Republican Party’s presidential nomination. Only two months ago, it seemed plausible that Romney might not reach the 1,144 delegate threshold until later this summer.

After a slow start, the Republican presidential campaign is ratcheting up in Iowa. Former Minnesota Governor Tim Pawlenty formally announced his candidacy in Des Moines today. Over the weekend former Godfather’s Pizza CEO Herman Cain made his campaign official too.

Arguably the biggest news of the past few days was Indiana Governor Mitch Daniels ruling out a campaign. Many Republican insiders had hoped he would beef up the weak declared field against President Barack Obama.

Links, quotes, and analysis are after the jump.

Donald Trump’s decision not to run for president put the Republican Party of Iowa in an awkward position, because he was supposed to keynote the party’s June 10 Lincoln dinner fundraiser. While Iowa GOP officials waited to hear whether Trump would keep his promise, even WHO television reporter Dave Price (a favorite among conservatives) couldn’t get a call back seeking comment. The state party finally got the bad news today and released this statement:

Earlier today the Iowa GOP was informed that Mr. Trump will not attend and keynote the June 10 Lincoln Dinner. Citing Mr. Trump’s unique appeal and the close proximity to the event, the Iowa GOP has decided to cancel the 2011 Lincoln Dinner.

Iowa GOP Chairman Matt Strawn issued the comment below following Mr. Trump’s decision to cancel his appearance at the Lincoln Dinner.

“In Iowa, your word is your bond. We are disappointed that Mr. Trump has chosen not to honor his commitment to Iowa Republicans.”

I know three weeks isn’t a lot of time, but I’m surprised party leaders couldn’t find some other well-known Republican to step up at the last minute. The Iowa GOP probably has already incurred printing and other expenses related to renting the Polk County Convention Complex for the event. Now money collected for record ticket sales will have to be refunded.

Maybe Iowa Republicans are better off not hitching their wagon to that horse, though. People with an unfavorable view of Trump greatly outnumber those who view him favorably, according to several recent national polls.

UPDATE: How bizarre.

On Friday, apparently stung by criticism from the spurned Iowans, Trump offered to travel to Iowa and speak if the Republicans would change their minds and hold the dinner.

“I promise you that my speech will be fantastic. My word is my bond,” he wrote to Matt Strawn, chairman of the Iowa Republican Party. […]

The state party’s response was essentially thanks, but no thanks. […]

“Iowa Republicans have moved on,” is all party spokesman Casey Mills had to say Friday afternoon.

A Trump aide released a copy of the letter, in which the tycoon said he had thought it would be inappropriate for him to give the speech once he decided not to run for president.

“I truly believe that this honor should be given to one of the other candidates or potential candidates, who could use this invaluable opportunity to get their word out,” he wrote. “I was very surprised and saddened to read that you canceled the event, and hence, called you immediately to let you know that if you wanted me to be there, I would be ready, willing and able.”

I could never understand why anyone thought Donald Trump was serious about running for president. A notorious germaphobe is not going to give up a show on network television in order to work the Iowa Republican house party and county fair circuit. Even if he did, his donations to various Democrats and assorted socially liberal statements would sink him in a Republican primary.

Anyway, Trump confirmed today that his recent speeches and press conferences were just a massive publicity stunt he is not running for president in 2012. President Barack Obama’s team will be disappointed; Trump replaced former Alaska Governor Sarah Palin as the candidate they would most like to run against.

Dave Weigel sees the Republican Party of Iowa as the second-biggest loser from Trump’s aborted presidential campaign. Trump is scheduled to headline the Iowa GOP’s Lincoln dinner on June 10. (Weigel says the Regnery publishing house is the biggest loser, because they have a Trump policy book scheduled to come out this summer.)

Iowa Republicans are desperate to get serious candidates out here campaigning. Presidential hopefuls and their PACs bring money to county Republican party committees and GOP statehouse candidates. Governor Terry Branstad’s big message at his weekly press conference this morning was that the race is wide open and everyone has a shot in Iowa, not just social conservatives. Branstad has said he won’t endorse a presidential candidate before the caucuses.

Any thoughts about the Republican race for the presidency are welcome in this thread. After the jump I’ve posted excerpts from a guest editorial in the Sunday Des Moines Register by the former chair of the New Hampshire Republican Party. He claims Iowa Republicans “have marginalized themselves.”

P.S. I’ve never been a fan of Lawrence O’Donnell, but he was right to say that NBC executives should have revealed earlier this spring whether the network had renewed Trump’s “Celebrity Apprentice” for another season.

P.P.S. Seth Meyers got in some good Trump jokes at the White House Correspondents Dinner last month.
