Battle for Senate control a toss-up with a few seats left to be called

The morning after Election Day in the 2022 midterms, control of the Senate remains a toss-up. As of Wednesday afternoon, Democrats had secured 48 seats and Republicans had 49 seats, with four races yet to be called, CBS News projects.

The Georgia race will go to a runoff in December between Sen. Raphael Warnock and Republican challenger Herschel Walker, after neither cleared 50%. CBS News characterizes Nevada as a toss-up, and Arizona as leaning Democrat. 

Alaska, where three candidates are on the ballot in a ranked-choice voting system, had not yet been called early Wednesday, but CBS News projects it will stay in Republican hands.

Wednesday morning, CBS News projected the Wisconsin race will go to Republican Sen. Ron Johnson. Among other battleground states, Republicans will win Florida, Ohio and North Carolina, while Democrats will win in Colorado, New Hampshire and Pennsylvania, CBS News projects.
