McCaskill, speaking on MSNBC, was asked what advice she would give to Democrats facing tough reelection fights.
"On the other side it's a mess. I mean they really have a civil war in their party right now," McCaskill said on 'Morning Joe.' "Joe your guys are fighting with each other. You've got people who are willing to compromise and understand the beauty of compromise and then you've got people like [Sen. Ted Cruz (R-Texas)] and some of the others that just think that they want to drive as hard as they can off the right edge of the world."
The senator from Missouri recently won reelection against former Rep. Todd Akin (R-Mo.) whose controversial rape comments badly hurt his candidacy. McCaskill said
"It's the reason I could win —was cause frankly they nominated a flawed candidate that was so extreme,"McCaskill said. "But it wasn't what Todd Akin said, it's what he believed. And that is the base of the Republican party right now."
Cruz recently joined in Sen. Rand Paul's (R-Ky.) filibuster of John Brennan's nomination for CIA director. In response, Sen. John McCain (R-Ariz.) referred to Paul and Cruz and a few other Republicans as "wackos."
