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.

Polls closed across Iowa at 9 pm, and I will update this post periodically as results come in from around the states. Any comments related to today’s elections are welcome in this thread.

P.S.- As expected, Wisconsin Democrats fell short in their effort to recall Republican Governor Scott Walker.

UPDATE: Results are after the jump.  

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.

The Iowa Democratic Party and Republican Party of Iowa held county conventions today. After the jump I’ve posted some notes on where Iowa politicians and candidates spent the day, and which Democrats addressed the Polk County Democratic convention. I left the convention during the lunch break, because delegates had finished most of the day’s business, including all work on the platform. However, the Polk County Republican convention was still going strong at this writing (around 5 pm).

This is an open thread; all topics welcome, especially county convention stories from today or years past.

Rick Santorum destroyed the competition in today’s Kansas caucuses, winning 52 percent of the vote to 21 percent for Mitt Romney, 14 percent for Newt Gingrich and 13 percent for Ron Paul. Romney swept the delegates at stake yesterday and today in the Guam and Northern Marianas Islands caucuses. Romney also won the Wyoming caucuses and most of the delegates from the Virgin Islands.

BONUS POTENTIAL FLAMEWAR TOPIC: Kevin Drum makes a counter-intuitive case: Return of the Jedi is the best Star Wars movie, especially if you take out the 10 minutes of horrific Ewok sequences. Thoughts?

First-term State Representative Kim Pearson announced today that she will not seek re-election in the new Iowa House district 30.

Jim Carley announced last week that he is running as a Republican in the new Iowa House district 30. Carley’s background is typical for a GOP statehouse candidate, but his announcement was unusual in one respect. A Republican incumbent already represents Iowa House district 30, and State Representative Kim Pearson has not decided yet whether to seek re-election.

Comments from both candidates about a possible primary contest are after the jump.
