The Iowa Senate convened for its 2022 session on January 10 with 32 Republicans and eighteen Democrats. Twelve senators are women (seven Democrats and five Republicans), up from eleven women in the chamber prior to the 2020 election and double the six women senators who served prior to the 2018 election.
I enclose below details on the majority and minority leadership teams, along with all chairs, vice chairs, and members of standing Iowa Senate committees. Where relevant, I’ve mentioned changes since last year’s legislative session. The biggest change: Republican Dave Rowley was elected in December to succeed Republican Zach Whiting, who resigned to take a job in Texas.
All current state senators are white. The only African American ever to serve in the Iowa Senate was Tom Mann, elected to two terms during the 1980s. No Latino has ever served in the chamber, and Iowa’s only Asian-American senator was Swati Dandekar, who resigned in 2011.
Some non-political trivia: the 50 Iowa senators include two Smiths, a Democrat and a Republican, and two Taylors, a Democrat and a Republican. As for first names, there are three Jeffs and two men each named Zach, Craig, Mark, Dan, Jim, and Tim.
Four of the last six general elections in Iowa were GOP waves, as you can see from the large number of Republican senators with relatively little seniority.
