Getting out the vote early was a major theme of President Barack Obama’s campaign rallies in Urbandale and Sioux City yesterday. Democratic candidates for other offices need a strong early vote as well, but there’s no sign the president is concerned about electing Democrats up and down the ticket.

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 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?
