Outstanding ballots in two states and a runoff election in a third have left control of the Senate up in the air, with Arizona and Nevada racing to count votes on Thursday and rival candidates in Georgia gearing up for another four weeks of campaigning.
Democrats were cautiously optimistic Sen. Mark Kelly's lead would hold in Arizona and in Nevada, where Sen. Catherine Cortez Masto is trailing, they think that mail ballots from urban areas will help catch them up. Some Republicans privately agreed their candidates could lose, but others in the GOP expressed confidence that Blake Masters would pull through in Arizona and Adam Laxalt would stay ahead in Nevada.
