Iowa House and Senate candidates were required to file their last pre-election campaign finance reports on Friday. In stark contrast to four years ago, Republicans are outspending Democrats in most of the contested state Senate districts. (I’ll address spending in the key Iowa House races in a different post.)

Currently, there are 25 Senate Democrats, 23 Republicans, and one independent. If former GOP Senator David Johnson makes good on his promise to remain an independent in 2017, and Democrats win the December special election to replace the late Senator Joe Seng, Republicans would need to pick up three seats to gain control of the upper chamber for the first time since 2004.

I enclose below in-kind contribution figures for the Senate districts expected to be in play next Tuesday. Candidates running elsewhere did not report large in-kind contributions from their respective parties.

Iowa is blessed with an unusually large number of competitive state legislative districts, thanks to our non-partisan redistricting process. Most election years, at least half a dozen Iowa Senate seats and twice as many House seats are in play. Campaign finance reports showing where candidates and party leaders are spending the most money provide the best clue on which legislative races are worth watching.

That said, most years at least one little-noticed candidate pulls off a big upset in an Iowa House or Senate district neither party was targeting. Now-disgraced Kent Sorenson won his first race in 2008, taking a House seat that had been considered safe for Democrats. Two years later, Kim Pearson got no help from GOP leaders en route to winning a House seat where the Democratic incumbent had been unopposed the previous election. Republican Mark Chelgren won an Ottumwa-based Senate district for the first time by ten votes. That seat had been considered so safe that the Democratic incumbent was knocking doors for a colleague in another district during the final weekend. I learned later that internal GOP polling had Chelgren almost 20 points down a couple of seeks before the election.

I can’t shake the feeling that in this strange campaign with two unpopular presidential nominees, something weird will happen in a down-ballot race no one is watching. So before I get back to Bleeding Heartland’s last few battleground Senate and House race profiles, a few words on why I feel a race in Iowa’s southeast corner could produce a shocking result.
