The state Senate voted 21-12 along party lines to sign off on GOP-authored maps that would likely strengthen Republican majorities in both houses of the Legislature over the coming decade.

The maps next head to the Assembly, which is expected to take them up Thursday. Gov. Tony Evers has vowed to veto the plans, and it’s expected the courts will ultimately put new lines in place for the 2022 election.

“Republicans’ new gerrymandered maps are modeled after the same gerrymandered ones we’ve had for a decade,” Evers tweeted today. “I won’t sign them. Wisconsinites want and deserve #fairmaps now.”
