MADISON — State Senator Mark Spreitzer (D-Beloit) was elected this week by his Democratic colleagues in the Wisconsin State Senate to serve as the Senate Democratic Caucus Chair in the 2025-2026 legislative session. 

“I am honored to be elected to serve as the Senate Democratic Caucus Chair,” Spreitzer said following the election in a statement. “The 2025-2026 legislative session represents a tremendous opportunity to continue to move Wisconsin forward, and I will continue to work with my colleagues on both sides of the aisle on behalf of the people of our state. 

“I look forward to working with our leadership team to build on the successes of last week — where Senate Democrats flipped all four competitive seats in the State Senate, despite national headwinds — and put ourselves on a clear and direct path to winning an 18-seat majority in 2026. With additional Democratic legislators elected in both the State Senate and State Assembly, it is clear from the results of this fall’s elections that the people of Wisconsin are supportive of our shared priorities for the state. I am excited to see the collective impact that our caucus will have with more members and a stronger voice in the State Capitol.

“I also want to take a moment to thank Senator Chris Larson for his service to our caucus as Caucus Chair over the past two years. He is a passionate leader who has always been a strong advocate for his community, our shared values, and our state. I look forward to continuing to serve together in the State Senate. 

“I thank my colleagues for their support. I am excited to get back to work to advance the values that we share as Wisconsinites.”

Spreitzer was elected to represent the 15th Senate District in the State Senate in 2022, and served as the Senate Democratic Caucus Vice-Chair from December 2023 to November 2024. Senator Spreitzer previously served as the State Representative for the 45th Assembly District from 2015-2023, and served as the Assembly Democratic Caucus Chair from 2016-2022.
