Some sobering facts about the bloodbath that was the 2016 election in Iowa:

Donald Trump carried eighteen state Senate districts that had voted for President Barack Obama in 2012.*

Eleven of those eighteen were even-numbered districts, which are on the Iowa ballot in presidential election years.

The four Republicans who already represented Obama/Trump districts all easily won another term in the Iowa Senate.**

But six of the seven Democratic senators up for re-election in Obama/Trump districts lost: Majority Leader Mike Gronstal (Senate district 8), Mary Jo Wilhelm (Senate district 26), Brian Schoenjahn (Senate district 32), Steve Sodders (Senate district 36), Tom Courtney (Senate district 44), and Chris Brase (Senate district 46).

With Republicans now enjoying a 32-18 majority in the upper chamber, Democrats need to win back at least a few Obama/Trump seats next year to have a realistic chance of regaining Iowa Senate control after the next round of redistricting.

Democrats have been actively campaigning in Senate districts 8 and 44 for some time. Now GOP State Senator Jeff Edler has a strong challenger in Senate district 36.

After several months of recruiting efforts, Republicans finally have a candidate willing to run against two-term State Senator Mary Jo Wilhelm in Iowa Senate district 26. This race is among a half-dozen or so contests that will determine control of the upper chamber after the 2016 elections. Since Iowans elected Governor Terry Branstad and a GOP-controlled state House in 2010, the 26 to 24 Democratic majority in the state Senate has spared Iowa from various disastrous policies adopted in states like Kansas, Wisconsin, Michigan, Ohio, and Pennsylvania. Of the senators who make up that one-seat majority caucus, Wilhelm was re-elected by the narrowest margin: 126 votes out of nearly 31,000 cast in 2012.

I enclose below a map of Senate district 26, a review of its voter registration numbers and recent voting history, and background on Wilhelm and challenger Waylon Brown. Cautionary note: although Brown is the establishment’s pick here, he is not guaranteed to win the nomination. “Tea party” candidates won some upset victories in the 2012 Iowa Senate Republican primaries, notably Jane Jech against former State Senator Larry McKibben in Senate district 36 and Dennis Guth against former State Senator James Black in Senate district 4.

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.

 . . but it's debateable how good the polling of House 71 is.

I got a call last evening on my cell which is issued to a number (I thought) in the Story County phone exchange.  It's from 801-685-8913, Murray, Utah, from "National Polling". Basic demographical data is asked, and then they ask me if I know these two names: Mark Smith & Jane Jech. Hell, no, I say. 

Okay, moving on, whom do you support for Governor, Senate . . etc. Operator specifically names *all* the names on ballot for each race, with party affliation. How likely am I to vote; what am I registered as? 

Getting back to Smith and Jech, do you like/dislike either? Whom will you vote for, Mr. Smith, the Democrat, or Ms. Jech, the Republican?

Thank you, end of call. 

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.

Candidates for the Iowa legislature were required to submit campaign finance disclosure reports on October 19 and November 2. The Schedule E forms on "In-Kind Contributions" contained the most interesting numbers, because they showed how Democratic and Republican party leaders are allocating resources across the battleground districts.

After the jump I've enclosed in-kind contribution figures for the Senate districts expected to be in play tomorrow. Candidates running in other Senate races did not report large in-kind contributions from their respective parties.
