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.

Happy 4th of July to the Bleeding Heartland community! I am celebrating the occasion with photos of red, white, and blue Iowa wildflowers. Click “there’s more” to view oswego tea, white snakeroot, and blue vervain.

The heat has been oppressive across Iowa lately. This afternoon I felt sorry for everyone in the Windsor Heights July 4 parade, including Representative Tom Latham, Representative Leonard Boswell, State Representative Chris Hagenow, his Democratic challenger Susan Judkins, and Democratic Iowa Senate candidate Desmund Adams.

I hope everyone stays safe and hydrated, and I am thinking of the veterans for whom today is a difficult holiday.

This is an open thread.

At least 200 people gathered on the west steps of the Iowa State Capitol Monday evening for a rally and vigil marking one month since Trayvon Martin’s killing in Floriday. After the jump I’ve posted a few notes from the event, along with links about the impact of Martin’s death on the debate over proposed “stand your ground” legislation in Iowa.

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 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?

It’s been years since a pro-choice moderate Republican represented any Iowa House and Senate district in the Des Moines suburbs. In this June’s GOP primary in Senate district 22, we’ll find out whether a mainstream Republican stands a chance against a loud voice on the party’s social conservative wing.

Two-term State Senator Pat Ward will face at least one Republican primary challenger in the new Iowa Senate district 22, covering Waukee, Clive, Windsor Heights and part of West Des Moines. The lead pastor at a large Waukee church announced his candidacy yesterday.
