Wisconsin Republican U.S. Rep. Mike Gallagher announced Friday that he won't run for U.S. Senate in 2024 against Democratic U.S. Sen. Tammy Baldwin, leaving an open GOP field with no declared candidates in the battleground state.
Gallagher was the highest profile Republican said to be considering a run against Baldwin, who is seeking a third term after an 11-point win in 2018. Baldwin is viewed as a formidable opponent due to her strong showing six years ago, her high profile across the state and her ability to raise money.
