"This polarization gets so out of hand that it becomes the theater of the absurd," said Levin, characterizing the gridlock in Washington, D.C., that has brought the federal government to the brink of shutdown at least twice so far this year.

Levin and Peters stood alongside their Republican colleague from Michigan, Rep. Candice Miller, in a joint appearance before the Detroit Economic Club.

Miller said that despite vastly different views on policy, the three lawmakers from Michigan manage to get along with little bickering.

"All three of us get along personally very well, but we have huge policy differences," said Miller. "There's a clash of ideologies, and I have a very different idea of how we get the economy going than my colleagues."
