Rep. Mike Gallagher (R-Wis.) announced on June 9 that he will seek reelection to the House and not challenge Sen. Tammy Baldwin (D-Wis.) for the U.S. Senate in 2024, leaving the GOP field in the swing state open.
Gallagher was the most prominent Republican rumored to be contemplating a run against Baldwin, who is seeking a third term after a 2018 victory by 11 points. Baldwin is regarded as a formidable opponent due to her impressive performance six years ago, her high profile throughout the state, and her fundraising prowess.
