UPDATE: Governor Kim Reynolds set the special election for Tuesday, December 14. Original post follows.

Republican State Senator Zach Whiting has resigned from the Iowa Senate to take a job in Texas, nwestiowa.com reported on October 29. In a statement, Whiting said he was proud of his service in the legislature and grateful to constituents, but could not pass up the opportunity to work for the Texas Public Policy Foundation, a conservative advocacy group.

Whiting was a staffer for U.S. Representative Steve King before winning a three-way GOP primary and the 2018 general election in Iowa Senate district 1. The previous incumbent, David Johnson, did not seek re-election that year. He had left the Republican Party to become an independent in the summer of 2016, in protest of the GOP nominating Donald Trump for president.

Governor Kim Reynolds will soon schedule a special election in November or December to fill the remainder of Whiting’s term, which runs through 2022. Senate district 1 includes all of Lyon, Osceola, Dickinson, Clay, and Palo Alto counties. Whoever wins the GOP nominating convention will almost certainly become the next senator. The district is among the reddest in Iowa, with nearly three times as many registered Republicans as Democrats.
