Democrats hold Colorado, New Mexico Senate seats; GOP keeps West Virginia

Democrats locked down two more Senate seats Tuesday night, with CBS News projecting wins in Colorado and New Mexico. Republicans answered with a hold of their own, keeping West Virginia after a successful reelection bid there.

The three calls add fresh bricks to a Senate map that has been stacking up fast all evening. CBS News characterized the projections as early, with the outlet saying more was still to come.

It's the second wave of Senate results in under an hour. Before Colorado and New Mexico landed, Democrats had already kept New Hampshire, where Chris Pappas beat Republican John E. Sununu to take the seat held by retiring Senator Jeanne Shaheen. Pappas becomes the first openly gay man elected to the Senate, according to the Associated Press and CNN projections.

Republicans had their own run of holds. Ashley Moody won Florida's special election, Andy Barr took Kentucky and Harriet Hageman prevailed in Wyoming, per the Associated Press and Fox News Decision Desk. Earlier, Kevin Hern — a four-term congressman endorsed by President Donald Trump — won Oklahoma's Senate race, the seat previously held by Markwayne Mullin.

Down the ballot, the night delivered a headline-making first. Democrat Keisha Lance Bottoms is projected to win Georgia's governor's race over Republican Rick Jackson, which would make her the state's first Black governor and its first woman governor — and the first Black woman elected governor in US history, per Decision Desk HQ and CNN. Democrats also notched their first House flip of the night in North Carolina's 11th District, where Jamie Ager is set to beat Republican Jennifer Balkcom.

More Senate calls are expected as the night runs on.
