Competitive primaries happened yesterday in several of the Iowa Senate districts that will determine control of the upper chamber for the next two years. Full results are on this page of the Secretary of State’s website.

My first take on the general election match-ups is below. I still see Democrats favored to hold their majority, with a decent chance of expanding it.

Polls close at 9 pm, and I’ll be updating this post regularly with primary election results. Rumor has it that turnout was relatively low, even on the Republican side where there are hard-fought primaries for U.S. Senate and the third Congressional district. According to the Polk County Auditor’s office, as of this afternoon only 1,506 absentee ballots had been requested and 1,350 absentee ballots received for today’s GOP primary. Keep in mind that roughly half of all Republican voters in IA-03 live in Polk County, and six campaigns were competing for their votes. Not to mention that five U.S. Senate candidates should have been locking in early votes in Iowa’s largest county.

By comparison, 2,883 Democratic primary absentee ballots were requested in Polk County, and 2,296 of those returned by today. The lion’s share were from Iowa Senate district 17 in Des Moines, where three candidates are seeking to replace Jack Hatch (2,475 absentee ballots requested and 1,950 returned). Democratic campaigns have long pushed early voting more than Republicans, but still–that’s a shocking failure to GOTV by the various Republican campaigns.

Share any comments about any Iowa campaigns in this thread, as well as any interesting anecdotes from voting today.

UPDATE: Polls are now closed and updates will continue after the jump.

Democrats appear to be in a strong position to hold their Iowa Senate majority, based on a first review of the landscape since the filing period for major-party candidates ended yesterday.
