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.

Iowa Senate Majority Leader Mike Gronstal is “fairly confident” going into this year’s state legislative elections, he told Mike Glover in a recent interview. He cited a “pretty good message” to take to voters as well as a “a slight advantage on the map” that will allow Democrats to play “a little less defense and a little more offense,” compared to 2012.

I agree with Gronstal that Democrats are better positioned now to hold their 26 to 24 majority in the upper chamber than they were at the same point two years ago. Follow me after the jump for a quick look at the eight districts the Senate majority leader expects to be targeted this fall.

It’s the time of year for blog posts about notable candidates and upcoming elections. Every politically engaged Iowan knows already that 2014 will be an unusually exciting year. We haven’t seen an open U.S. Senate race since 1974. The last time Iowa’s first Congressional district was open was in 2006. The last time Iowa’s third Congressional district was open was in 2002, but it wasn’t a wide open seat, since incumbent Representative Leonard Boswell moved into Polk County to run. Amazingly, 1940 was the “last time there was a Congressional race in Polk County without an incumbent seeking re-election.” All of Iowa’s statewide elected officials are up for re-election as well this year, and the secretary of state’s position may become open if Matt Schultz decides to go for the Republican nomination in IA-03.

Since Bleeding Heartland readers already know about the big Iowa races to watch, I want to focus today and tomorrow on the elections that are likely to determine control of the Iowa House and Senate in 2015 and 2016.  

A competitive Republican primary seems likely in Iowa Senate district 39, an open seat that will be one of the most important statehouse races in 2014. Michael Moore of Washington County has already launched his campaign, and two Republicans in Johnson County are thinking about the race. Royce Phillips is a former mayor and current City Council member in Tiffin. He is also pastor of the Tabernacle Baptist Church in Coralville. At a fundraiser for Johnson County Supervisor John Etheredge earlier this month, Phillips spoke publicly about a possible candidacy in Senate district 39. He confirmed by telephone today that he is familiarizing himself with the district and has had a “positive response” so far. Phillips added that he is more familiar with the House district 77 half of the district (which is in Johnson County) than with House district 78 (all of Keokuk and most of Washington Counties). I’ve posted a district map after the jump. Phillips has been active in local Republican politics for many years. He endorsed Mike Huckabee before the 2008 Iowa caucuses and Rick Santorum during the last election cycle.

Republican Party of Iowa State Central Committee member Bob Anderson has also been mentioned as a possible candidate in Senate district 39. He told me today that he is “analyzing” and “considering it seriously” but did not specify a timetable for announcing a decision. Anderson has also been active in Republican politics for a long time and chairs is the past chair of the Johnson County GOP Central Committee. He is one of the few GOP State Central Committee members who did not publicly endorse a presidential candidate before the 2012 Iowa caucuses.

No Democrat has yet announced plans to run in Senate district 39. State Senator Joe Bolkcom told the Iowa City Press-Citizen’s Adam Sullivan recently, “We’re working on recruitment there now. It’s on our list of likely opportunities to pick up a seat.”

The Daily Kos Elections team has been compiling 2012 presidential election results by state legislative district as well as by Congressional district. Yesterday the Iowa numbers were added to the database. You can view Google documents with raw vote totals and percentages for Barack Obama and Mitt Romney by Iowa Congressional district here, by Iowa Senate district here, and by Iowa House district here.

Looking closely at the presidential vote in the legislative districts provides some insight about where the competitive Iowa statehouse races might be next year. After the jump I’ve highlighted some key data points related to the Iowa Senate races. Later I will post a separate diary with first thoughts about the Iowa House districts.

Via John Deeth’s blog I saw that Republican Michael Moore has announced his candidacy in Iowa Senate district 39, a swing seat being vacated by Senator Sandy Greiner.

I had expected GOP State Representative Jarad Klein to step up for this race, but he quickly took himself out of contention. You can’t blame him for wanting to stay where he’s safe and warm. Iowa House district 78, which Klein currently represents, has a Republican voter registration advantage of more than 2,000, while Senate district 39 contains 13,342 registered Democrats, 13,341 Republicans, and 16,194 no-party voters.

Moore has a long record of civic involvement in Washington County. I’ve posted his official bio and first press release after the jump. His campaign is on the web here. I wouldn’t be surprised if some Republican from the party’s “Liberty” wing ends up competing against Moore in the June 2014 primary.
