Thanks to Iowa’s non-partisan redistricting process, we have an unusually large number of competitive state legislative districts. In any given general election, depending on candidate recruitment, between one dozen and two dozen of the 100 Iowa House districts could be up for grabs. Democrats and Republicans spend big money on a much smaller number of districts; this year, only seven Iowa House races involved a large amount of television advertising. But the parties and candidates invest in direct mail and/or radio commercials in many more places than that.

Republicans go into election day favored to hold their Iowa House majority, which now stands at 53 seats to 47. Carolyn Fiddler has pegged seven “districts to watch” at her Statehouse Action blog, and in September, the Des Moines Register’s Jason Noble discussed five districts he viewed as “key to Iowa House chamber control.” I see the playing field as much larger.

Follow me after the jump to review 20 Iowa House seats that will determine control of the chamber for the next two years.

Caveat: most years, there’s at least one shocking result in an Iowa House district neither party had their eye on. I’m thinking about Tami Weincek defeating a longtime Democratic incumbent in Waterloo in 2006, Kent Sorenson defeating a Democratic incumbent in Warren County in 2008, three Democratic state representatives who had run unopposed in 2008 losing in 2010, and Democrat Daniel Lundby taking out the seemingly safe Republican Nick Wagner in the Linn County suburbs in 2012. Wagner had run unopposed in the previous election.

So, while I don’t expect any of the “favored” seats discussed below to change hands, I would not rule out a surprise or two. That would be excellent news for the stealth challenger’s party.

The filing period for general election candidates in Iowa closed last Friday, so it’s a good time to review where candidates not representing either the Democratic or Republican Party are running for office. The full candidate list is on the Iowa Secretary of State’s website (pdf(. After the jump I discuss all the federal, statewide, and state legislative races including at least one independent or minor-party candidate. Where possible, I’ve linked to campaign websites, so you can learn more about the candidates and their priorities.

Rarely has any Iowa election been affected by an independent or third-party candidate on the ballot. Arguably, the most recent case may have been the 2010 election in Iowa’s first Congressional district. Final results showed that Democratic incumbent Bruce Braley defeated Republican challenger Ben Lange by 4,209 votes, while conservative candidates Rob Petsche and Jason Faulkner drew 4,087 votes and 2,092 votes, respectively.

Any comments about Iowa’s 2014 elections are welcome in this thread.
