This post has been updated with unofficial results from the November 5 election, as well as the final pre-election campaign finance disclosures and absentee ballot totals as of November 2. Original post follows.

Republicans currently hold 34 Iowa Senate seats—the largest GOP contingent in that chamber since 1973. Democrats are not realistically contending to regain the Senate majority in November. So why pay any attention to these legislative races?

Although the most competitive state Senate races won’t determine control of the chamber, they could reveal a lot about each party’s strengths with certain kinds of voters. A good night for Republicans would indicate that the Trump-era realignment has moved further into Iowa’s former blue regions. A good night for Democrats could pull the GOP below the two-thirds threshold, which has allowed Senate Republicans to confirm all of Governor Kim Reynolds’ nominees without any support from the minority party.

This post highlights four state Senate districts at most risk of flipping, and another seven districts where even without a big investment by Democrats or Republicans, the results could shed light on broader political trends in Iowa. A forthcoming article will cover state House races to watch in 2024.

Iowans will elect 25 state senators today. Those races have attracted far less attention than this year’s Iowa House races, because Republicans have a lopsided 32-18 majority in the upper chamber and only a 53-47 advantage in the House.

Nevertheless, it’s important to keep an eye on the Senate races, because this year’s outcome will influence Democratic prospects under the new map coming in 2021.

This overview covers five districts where both parties are spending six-figure amounts, seven districts where Republicans spent a significant amount, and four more districts where the results could shed light on political trends in various parts of the state, even though neither Democrats nor Republicans targeted the race.

Democrats continue to land solid candidates for Iowa Senate seats, despite the GOP’s 32-18 majority in the upper chamber.

This week Warren Varley, a farmer and attorney, made his campaign official in Senate district 10, where GOP incumbent Jake Chapman has not faced a serious challenge before.

After securing an early endorsement from his onetime boss U.S. Senator Chuck Grassley, David Young has landed another vote of confidence from a Republican heavyweight in his bid to represent Iowa’s third Congressional district.

Young campaign staff confirmed on June 7 that former Governor Terry Branstad, who is now U.S. ambassador to China, donated to the campaign this quarter. Young has mentioned Branstad’s contribution in conversations with politically active Iowans, according to a source who saw the former member of Congress recently.

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.  

I’m posting the weekend thread early, because the filing period for primary election candidates in Iowa closed this afternoon. The Secretary of State’s Office posted the full list of candidates here (pdf). John Deeth has been covering the filing on a daily basis all month at his blog. Some highlights from races I’m watching are after the jump.

This is an open thread; all topics welcome.

UPDATE: Gotta agree with Senator Chuck Grassley: the History Channel is useless.
