Sen. Mark Warner (D-VA) described Indiana Senate candidate Richard Mourdock, a tea party favorite, as having "wacky" ideas on bipartisanship.
Mourdock, who recently defeated six term Indiana Sen. Richard Lugar (R) in a primary race, said in May that he wanted bipartisanship to mean Democrats going along with Republicans.
"I think what Mr. Mourdock said is wacky," he told CNN's Candy Crowley. "I don't know what Constitution he wants to defend. The brilliance of the founding fathers were they set up a slightly dysfunctional government to start with -- checks and balances, independent House, independent Senate, independent President. You have to work together to find that common ground."
"The notion that this election is going to be so overwhelmingly for one side or the other, that there's going to be a clear picture and one party's, you know, going to be able to rule the roost, I just don't see that happening," Warner added.
