Fox News senior political analyst Brit Hume predicted on Tuesday that a "civil war" would erupt within the Republican Party if the GOP fails to capitalize on momentum and take control of the Senate from Democrats.

"The Republican establishment … got the nominees that they wanted, virtually across the board," Hume explained on Fox News' "America's Newsroom." "You didn't have any of these gaffes by Republicans … the key states in play all favor the Republicans."

"If they don't win this time, the eternal conflict in that party… will explode, in my judgment. The Tea Party people will say, 'All right, we did it your way this time. We did it all your way, basically, and we still didn't win. We're not going along anymore.' And there will be a civil war, I predict."

That war, Hume said, would also jeopardize Republicans' chances to win back the White House in 2016.

"The candidate who's running needs to be able to unite the party," he said. "It would be hard to do anyway. If they lose this midterm election in the sense of not getting the Senate… it'll be as bloody a set of recriminations as we've ever seen."
