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.

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.

Republicans saved the day for Iowa Senate Commerce Committee Chair Matt McCoy, providing most of the votes he needed to drag the nuclear energy bill over the line on Tuesday.

Expanding nuclear power is again a hot topic at the Iowa statehouse. It’s not clear whether Iowa Senate Commerce Committee Chair Matt McCoy can find the votes he needs to advance House File 561. McCoy announced last week that new language in the bill would protect consumers and satisfy a majority of his committee members. However, opponents say the changes address only one of many problems in a bill that would primarily benefit MidAmerican Energy at the expense of its ratepayers. McCoy was forced to delay consideration of House File 561 on March 8, but he is expected to bring up the bill before his committee sometime this week–if he has the votes.

Follow me after the jump for analysis on the prospects for passing House File 561 and the merits of the bill.

The Democratic-controlled Iowa Senate passed two bills today favored by corporate agricultural interest groups. House File 589, the notorious “ag gag” bill, seeks to prevent whistleblowers from reporting alleged abuse at agricultural facilities. Senate File 2172 would reduce the number of sows that confined-animal feeding operations need to report for manure management purposes. Details on the bills and how senators voted are after the jump.

UPDATE: Bypassing normal legislative procedures, the Republican-controlled Iowa House also passed the “ag gag” bill on February 28. Scroll down for details on how the state representatives voted.  

Republican State Senator Merlin Bartz confirmed this week that he will run for re-election in the new Iowa Senate district 26. His race against Democratic incumbent Mary Jo Wilhelm is probably a must-win for Senate Democrats in order to preserve their majority. After the jump I’ve posted a district map. Bleeding Heartland previewed the Bartz/Wilhelm matchup here.

Bartz has given Iowa progressives plenty of reasons to want him gone, from encouraging county recorders to ignore a Supreme Court ruling to trying to block the most significant water quality regulations of the last decade. Bartz’s record is so bad that even learning he “has performed for over 35 years in north and northeast Iowa with various dance bands” didn’t give me any sympathy for the guy. Democrats who live within striking distance of Worth, Mitchell, Floyd, Howard, Chickasaw, Cerro Gordo, or Winneshiek counties have a golden volunteer opportunity here.

P.S. to the Des Moines Register’s editorial staff: that last link was to William Petroski’s blog post. I liked the dance band detail. When you read something interesting on a blog, it won’t kill you to link to it. I mention this because your January 15 comment on Bartz’s crusade against “obsolete” laws reads a lot like Bleeding Heartland’s post from January 10.  

The November special election in Iowa Senate district 18 confirmed that Democrats will maintain a 26 to 24 majority in the upper chamber during the legislature’s 2012 session, set to begin on January 9.

Senate Democrats and Republicans recently announced updated committee assignments. Majority and minority leadership teams are after the jump, along with all members of standing committees. I’ve also noted which senators are up for re-election in 2012 and which are retiring next year.

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.

Only one Iowa Senate race in 2012 will pit Republican and Democratic incumbents against each other. First-term Democrat Mary Jo Wilhelm confirmed this week that she will seek re-election in the new Senate district 26. Her likely opponent is four-term Republican Senator Merlin Bartz. Follow me after the jump for a district map and first take on this matchup.

As a bonus, this post also covers the strangest failure to do basic damage control I’ve seen from a political veteran.
