MADISON, Wis. (AP) — A second Republican leader in the Wisconsin Legislature announced on Thursday he will not seek reelection this fall, signaling a possible seismic shift in the state's political landscape. Senate Majority Leader Devin LeMahieu's retirement follows that of Assembly Speaker Robin Vos, the longest-serving speaker in Wisconsin history.

LeMahieu expressed a desire for a new chapter in his life in his retirement announcement. Both leaders' departures come in the shadow of newly drawn district boundaries that favor Democrats, who are increasingly optimistic about flipping the state Senate.

Wisconsin Democratic Party Chair Devin Remiker remarked that these retirements should serve as a warning for other Republicans, while speculations arise about the challenges the GOP might face going into the elections.

The upcoming election year could prove to be particularly tough for Republicans across the nation, with a growing number of GOP lawmakers opting not to run again, alongside a decisive shift in the state's governance after recent political changes, including a Democratic majority in the Wisconsin Supreme Court.

With Democrats needing to secure only two additional seats in the Senate, LeMahieu's exit underscores the GOP's awareness of the mounting pressure as the political tide potentially shifts in Wisconsin.
