The filing period for general-election candidates closed on August 15. You can view the full candidate list for federal and state offices on the Iowa Secretary of State’s website. John Deeth briefly reviews all 100 House races here. Next month, I’ll be posting on the most competitive Iowa House races.

For today, I’m interested in what appears to be a pattern of Republicans letting Iowa House seats go in battleground Iowa Senate districts. I suspect a strategy is in play to depress GOTV in the more Democratic halves of these districts.  

In any given general election, roughly a dozen or two of the 100 Iowa House districts are in play. A first look through the list of candidates who qualified for the primary ballot suggests that this year, fewer Iowa House districts will be competitive than in 2010 or 2012. Republicans have failed to field a candidate in 32 of the 47 Democratic-held House districts. Democrats have failed to field a candidate in 26 of the 53 Republican-held House districts.

Although a few of these districts may see major-party candidates nominated through special conventions after the primary, it’s rare for late-starting candidates to have a realistic chance to beat an incumbent. (That said, two Iowa House Democrats lost in 2010 to candidates who joined the race over the summer rather than during the primary campaign.)

After the jump I’ve enclosed a full list of the Iowa House districts left unchallenged by one of the major parties. I highlighted the most surprising recruitment failures and what looks like a pattern of uncontested House seats in Senate districts that will be targeted by both parties, which may reflect a deliberate strategy. House incumbents with no fear of losing may slack off on GOTV in one half of a Senate district where every vote may count.

A future post will focus on the ten or fifteen Iowa House races likely to be most competitive this fall.
