Wisconsin’s powerful Republican Assembly leader says he hopes the liberal-controlled state Supreme Court adopts new constitutional legislative boundary maps, even as he slammed proposals from Democrats as “a political gerrymander” and threatened an appeal to the U.S.

Wisconsin’s powerful Republican Assembly leader said Tuesday that he hopes the liberal-controlled state Supreme Court adopts new constitutional legislative boundary maps, even as he slammed proposals from Democrats as “a political gerrymander” and threatened an appeal to the U.S. Supreme Court.

The court tossed Republican-drawn maps, long considered among the country’s most favorable to the GOP, and ordered new maps that do not favor one party over another. It said if the Legislature doesn’t adopt maps, the court will.

Assembly Speaker Robin Vos said Republicans have approached Democrats about passing new maps in the Legislature, but “we have not gotten a warm reception to that idea.”
