State Senator Brad Zaun endorsed Donald Trump for president last week.

What will he think of next?

If past experience is any guide, nothing that reflects a coherent political philosophy, and nothing that will help him attain the higher office he covets.

Five-term State Representative Pat Grassley announced on Twitter this morning that he will chair the Iowa House Appropriations Committee. The previous chair, Chuck Soderberg, retired from the legislature last month. I don’t know who else lobbied Speaker-Select Linda Upmeyer for this prize committee assignment, but I will update this post if I learn more.

The grandson of U.S. Senator Chuck Grassley, Pat Grassley was first elected to the Iowa House in 2006. He chaired the House Economic Growth and Rebuild Iowa committee in 2011 and 2012 and has chaired the House Agriculture Committee since the 2013 legislative session. He represents a safe Republican district covering Grundy County and parts of Hardin and Butler counties. Grassley’s most competitive re-election bid was the 2012 Republican primary in House district 50, after redistricting pitted him against then-colleague, State Representative Annette Sweeney.

Many Iowa politics watchers expect Grassley to run for secretary of agriculture in 2018, assuming the current incumbent Bill Northey seeks the Republican nomination for governor.

OCTOBER UPDATE: Upmeyer selected three-term State Representative Lee Hein to chair the House Agriculture Committee for the 2016 legislative session. Hein had previously been one of four assistant majority leaders.  

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.

Forty men and ten women currently serve in the Iowa Senate. No senators are African-American, Latino, or Asian-American.

Seventy-five men and 25 women currently serve in the Iowa House. Five state representatives are African-American and none are Latino or Asian-American.

Time for a look at how those numbers might change after the November election, now that primaries have determined the major-party nominees in all state legislative districts. Click here for the June 3 unofficial election results and here for the full list of candidates who filed to run in the primaries.

Polls closed across Iowa at 9 pm, and I will update this post periodically as results come in from around the states. Any comments related to today's elections are welcome in this thread.

P.S.- As expected, Wisconsin Democrats fell short in their effort to recall Republican Governor Scott Walker.

UPDATE: Results are after the jump.  

Polls are now open in Iowa's primary elections across the state and will close at 9 pm.

Any comments about Iowa races for Congress, state legislative, or county offices are welcome in this thread. I've posted lots of links after the jump to get the conversation going. I also extended the deadline for entering the primary election prediction contest.
