(Reuters) - Liberal challenger Jill Karofsky won a hotly contested race for the Wisconsin Supreme Court on Monday, beating a conservative incumbent in state elections marred by court challenges and worries about coronavirus health risks.

Karofsky was projected by the Associated Press to beat conservative incumbent Dan Kelly, who was endorsed by Republican President Donald Trump, for a court seat that could help decide future voting rights and redistricting issues in Wisconsin, a vital general election battleground.
