Evan Bayh wants out of Washington but wonders if the partisan bickering he leaves behind will one day be swept aside by a new PEROTRoss Perot riding a third-party tidal wave of public anger.

“If (voter) frustration continues to grow and the American people say ‘a pox on both your houses,’ then there’s some prospect for a third-party type movement,” the Democratic senator from Indiana told ABC’s Good Morning America.

Bayh hastens to add that he doesn’t believe that would really happen.

Why not? “I think that ultimately we can make progress within the two-party system,” he said.

Good luck.

FRANCE/Republicans and Democrats both catch blame. But Democrats, as the governing party, could suffer most in November’s congressional elections. Republicans did the suffering in 2006. Meanwhile, the conservative Tea Party movement has candidates from both sides rattled.
