Preliminary results from the Iowa Secretary of State’s website show that President Barack Obama defeated Mitt Romney in Iowa by 807,146 votes to 720,323 (51.89 percent to 46.31 percent) amid record participation of 1,555,570 voters statewide.

As expected, the president won a plurality of the vote in fewer Iowa counties this year than in 2008, but he did pick up one county that was a big surprise for me. Some thoughts about the presidential vote in Iowa are after the jump, along with maps showing which counties Obama, Romney, and John McCain carried. You can find vote totals for every county on the Iowa Secretary of State’s website.

Republicans maintained their Iowa House majority with either 52 or 53 seats, depending on what happens in one unresolved race.  

Now that almost all Iowa precincts have reported, I’ve enclosed more detailed results from the four Congressional races after the jump. All numbers come from this page on the Iowa Secretary of State’s website.  

Democrats are assured of maintaining their majority in the Iowa Senate, with one race headed for a recount and another to be decided in a December 11 special election.

Supporters of LGBT equality are celebrating yesterday’s votes for same-sex marriage rights in Maine, Maryland, and Washington, as well as Minnesotans rejecting a constitutional amendment designed to restrict marriage rights to heterosexuals.

The election also slammed the door on any prospect of overturning marriage equality in Iowa.

Polls close at 9 pm in Iowa, but there are already plenty of other election returns coming in to discuss. I’ll update this post after the jump throughout the evening. Spoiler alert: the media have already called Pennsylvanian for President Barack Obama.

10:10 pm: Iowa has been called for Obama. No path to 270 electoral votes remains for Romney.

12:34 am: Not all of the Iowa House races have been called yet, but it looks like Republicans may end up with a 53-47 majority, and several Democrats lost very close races. If the House Democrats had had the resources to contest more districts, they could have won a majority. Most of the money flowed to Iowa Senate candidates for obvious reasons.

1:09 am: Iowa Senate Democrats sound confident that they have won 26 seats. The last few results aren’t yet official on the Secretary of State’s website, however. Details are below.

WEDNESDAY: Unofficial returns show 1,558,252 Iowans cast ballots in the 2012 general election, an increase from 2008. That’s about 72 percent of the state’s eligible voters.

The campaign in Iowa’s fourth Congressional district set records for fundraising by a U.S. House incumbent and challenger in Iowa and attracted nearly $5 million in spending by outside groups. For weeks, television stations around the district have been saturated with ads for and against five-term Representative Steve King and Democratic challenger Christie Vilsack.

A final news roundup on IA-04 is after the jump, including Vilsack’s key campaign themes and King’s closing message to voters.  

Whatever happens in tonight’s Iowa legislative races, one mystery will remain: why couldn’t Republicans recruit a stronger candidate to run against Mike Gronstal in Iowa Senate district 8?  

Given how much money Democratic and Republican leaders are spending on advertising in the Iowa Senate races, it’s unfortunate that so few of the television and radio commercials are available online. Both of the candidates in the battleground Senate district 30 (Cedar Falls/Waterloo) continue to set a good example for transparency, though.

The final tv ads supporting Senator Jeff Danielson and his Republican challenger Matt Reisetter are after the jump, along with other recent news from the campaign. Bleeding Heartland discussed these candidates’ previous ads here and here.

Happy election day, Bleeding Heartland readers! All comments about your voting experience or any campaign you’re watching are welcome in this thread. I’d like to hear more reports about radio and television commercials for Iowa House and Senate candidates. The parties have been spending a ton of money on those lately.

A lot of my friends went to see President Obama and Bruce Springsteen in the East Village of Des Moines last night. It looked like Paul Ryan drew a big crowd near the airport too. I’m standing by my prediction that Obama will win Iowa, but ARG did release a poll yesterday showing Mitt Romney ahead here by 49 percent to 48 percent.

The latest Iowa absentee ballot totals are after the jump, along with thoughts about how well Romney needs to do today to make up his early voting deficit.

I planned to write several posts this fall about the third Congressional district race between Representatives Tom Latham and Leonard Boswell. Instead, every time I sat down to write about the campaign, I found myself turning to other topics. Central Iowa radio and television stations have been so over-saturated with cookie-cutter attack ads against both candidates. If a political junkie like me finds it off-putting, I can’t imagine how disengaged other people feel when they hear the beginning of yet another negative commercial.

Neither Latham nor Boswell has offered a compelling case for re-election, but after the jump I review the main messages from both campaigns and from various outside groups that have been advertising in Des Moines and Omaha.

Going into election day two years ago, Representative Dave Loebsack appeared to be in real danger of losing his seat in Congress. The Democratic Congressional Campaign Committee was running attack ads against Republican challenger Mariannette Miller-Meeks, who had loaned her campaign about a half-million dollars in the absence of major financial support from the National Republican Congressional Committee. The American Future Fund was bashing Loebsack on television. Loebsack ended up winning re-election by only about 11,500 votes in what should have been a safe Democratic district. If not for the Iowa Democrats’ early voting program, Loebsack might have been swept up by the wave.

This year’s campaign in Iowa’s second Congressional district is winding up without the suspense of 2010. A final review of Loebsack’s race against Republican John Archer is after the jump.

Candidates for the Iowa legislature were required to submit campaign finance disclosure reports on October 19 and November 2. The Schedule E forms on “In-Kind Contributions” contained the most interesting numbers, because they showed how Democratic and Republican party leaders are allocating resources across the battleground districts.

After the jump I’ve enclosed in-kind contribution figures for the Senate districts expected to be in play tomorrow. Candidates running in other Senate races did not report large in-kind contributions from their respective parties.

Democratic candidates for the state Senate haven’t fared well in western Iowa lately, so the new Senate district 6 hasn’t been on my radar, even though it’s an open seat. However, campaign finance reports indicate that Democrats are not conceding this district, so I decided to post a profile of the race. Background on both candidates is below, along with a district map and some of the campaign rhetoric voters have been hearing.

Shortly before election day 2010, Representative Bruce Braley and his staff were sweating it. The Democratic Congressional Campaign Committee spent significant funds to help Braley fend off a ton of attack ads funded by conservative groups. Braley defeated Ben Lange by just 4,209 votes. If not for Iowa Democrats’ early vote program and the presence of two minor-party candidates on the ballot, Lange might be in Congress today.

This year, Iowa’s first Congressional district looks far less competitive. A final review of Braley’s rematch against Lange is after the jump, including some fireworks from the candidates’ Iowa Public Television debate last week.  

Many candidates for the Iowa House and Senate tout endorsements by outside groups in their campaign communications. Some of those groups pay for direct mail, phone calls, or even advertising supporting their endorsed candidates.

Iowa’s influential political action committees and advocacy groups have very different ways of getting involved in the state legislative campaign. Follow me after the jump for examples of four distinct strategies.

The Des Moines Register’s new poll by Selzer and Co is the latest survey to give no clear sign of whether voters will retain Iowa Supreme Court Justice David Wiggins on Tuesday.  

President Barack Obama and Republican Mitt Romney both headlined rallies in Dubuque today as two new polls showed the president ahead in Iowa.  

Three-time candidate for Iowa governor Bob Vander Plaats has made news this fall primarily on the “No Wiggins” campaign trail. However, the social conservative group he runs is supporting some Republican Iowa Senate candidates as well.

Last week the FAMiLY Leader launched radio advertising campaigns in two competitive Senate races–but notably, not in the district where Vander Plaats’ longtime right-hand man Matt Reisetter is running.  

What’s on your mind this weekend, Bleeding Heartland readers? More posts related to Tuesday’s elections are going up today and tomorrow, so after the jump I’ve enclosed a few links on stories not related to any political campaigns.

This is an open thread. Don’t forget to turn your clocks back one hour before you go to sleep on Saturday night.
