Now that we’ve all had a few days to take in the election results, candidates and political activists in both parties can reflect on how our time and money could have been better spent during the campaign. After the jump I’ve posted links about Republican and Democratic regrets.

This is an open thread: all topics welcome.

At this time four years ago, Barack Obama’s campaign had about 30 field offices up and running in Iowa, compared to six offices for Republican presidential candidate John McCain.

Obama’s campaign has had eight Iowa field offices open this summer and is rolling out another 26 offices around Iowa this weekend. So far, Mitt Romney’s campaign has ten Iowa field offices, in addition to the unified Republican headquarters in Urbandale.

After the jump, I compare the field office locations for each presidential campaign, grouped by Iowa Congressional district. Where relevant, I’ve also noted competitive Iowa House and Senate districts near the Obama and Romney field offices, although I doubt either presidential campaign will do much for down-ticket Democratic or Republican candidates.

The redistricting process and several Republican retirements have created many pickup opportunities for Iowa House Democrats. The devastating 2010 election left them nowhere to go but up in the lower chamber, where Republicans currently enjoy a 60 to 40 majority. Relatively few sitting House Democrats represent vulnerable districts.

Speaking to activists at the Polk County Democratic convention on March 10, I heard lots of optimism about the House races. After the jump I’ve posted some early thoughts on the seats up for grabs.

I’m posting the weekend thread early, because the filing period for primary election candidates in Iowa closed this afternoon. The Secretary of State’s Office posted the full list of candidates here (pdf). John Deeth has been covering the filing on a daily basis all month at his blog. Some highlights from races I’m watching are after the jump.

This is an open thread; all topics welcome.

UPDATE: Gotta agree with Senator Chuck Grassley: the History Channel is useless.

The state agency Iowa Workforce Development has replaced 36 field offices with hundreds of new “enhanced access” computer terminals this year.

Although the shuttered offices are unlikely ever to reopen, they may live on as talking points in many competitive Iowa House and Senate races next fall.

Former State Representative Tom Schueller is running as a Democrat in the new Iowa House district 58, setting up a likely rematch against first-term Republican Brian Moore.

County auditors have been certifying election results this week, and the Iowa House is almost certain to be split 60-40 in favor of Republicans. Three seats were determined by extremely narrow margins. Democrat Donovan Olson does not plan to seek a recount in House district 48, where he trails Chip Baltimore by fewer than 30 votes. Republican Roger Arthur does not plan to seek a recount in House district 18, where he finished 36 votes behind Andrew Wenthe. Republican Lannie Miller has not decided whether to ask for a recount in House district 7, but John Wittneben’s margin of 32 votes is unlikely to be overturned in a recount.

The Iowa Senate is headed for a 26-24 Democratic majority. Certified election results put Democrat Keith Kreiman 12 votes behind Mark Chelgren in Senate district 47, while Democrat Tod Bowman is 71 votes ahead of Andrew Naeve in Senate district 13. If I were Kreiman, I would ask for a recount to be sure, but even a tiny margin of 12 votes (0.06 percent of the votes cast in that Senate race) probably wouldn’t be reversed.

Jennifer Jacobs reported in the Des Moines Register,

Election results show that voters angry about the Iowa Supreme Court’s gay-marriage ruling played a role in defeating Kreiman.

In 2006, Kreiman won 71 percent of the votes in his home county, Davis County. This year, 774 more Davis County residents voted on judicial retention than in 2006.

Davis County was one of seven counties where the anti-retention vote was above 70 percent.

I suspect Mariannette Miller-Meeks’ strong Congressional campaign played at least an equally important role in Chelgren’s win. Senate district 47 includes Miller-Meeks’ home base, the Ottumwa area, and she worked extremely hard all year.

Senate Republican leader Paul McKinley tried to psych out Democrats this week by saying he has “thought about” trying to convince state senators to switch to the GOP: “I think there are individuals that we know that clearly were put in tough situations over the past two or three years and might be more prone to that, but we thought about it. We’ll analyze where we are and proceed accordingly.”

Two Democrats flipping together could give Republicans a majority in the upper chamber, but I very much doubt that will happen. The moderate Democrats in the Senate caucus have more pull with Senate Majority leader Mike Gronstal than they would as junior members of a Republican majority. Also, it’s not as if McKinley could promise party-switchers a smooth ride to re-election. U.S. Representative Parker Griffith of Alabama got crushed in a GOP primary this year after deserting the Democratic Party. An incumbent in a vulnerable Iowa Senate seat would not survive a Republican primary after voting for I-JOBS and all four of Chet Culver’s budgets.

Reading up on the carnage that was last week’s Congressional elections, I noticed that two House Democrats lost their seats despite having run unopposed in 2008. The unlikely losers were Rick Boucher in Virginia’s ninth district and Phil Hare in Illinois’ seventeenth district, including the Quad Cities area (though polls had shown Hare in trouble this fall).

I wondered whether any Iowa Democrats suffered the same fate. It turns out that three of the 13 Iowa House incumbents defeated last week did not have a Republican opponent in 2008. In each case, special circumstances may have exacerbated the generally bad environment for Democratic candidates this year.

Democrats suffered big losses in the Iowa House and Senate last night. Assuming no results change through recounts, the House is likely to switch from 56 Democrats and 44 Republicans to 59 Republicans and 41 Democrats. I’ve seen some online references to a 58-42 split, but that’s not how the count looks based on unofficial results posted on the Secretary of State’s website.

Democrats maintain control of the Iowa Senate, but their majority shrank from 32-18 to 27-23. Governor-elect Terry Branstad should easily be able to get his agenda through the Iowa House, and Senate Majority Leader Mike Gronstal may have trouble keeping his caucus united.

UPDATE: Late returns could change the outcome in two Senate seats; it’s possible the chamber could have a 25-25 split, or a 26-24 Democratic majority.

SECOND UPDATE: A few more races could switch as more absentee ballots come in. As of Wednesday evening, Democrat Tom Schueller is now trailing in House district 25 by about 150 votes.

Here’s my take on the seats that changed hands and the near-misses.
