Even experienced pols choke under the pressure of a high-stakes debate. Here, former Gov Tim Kaine invents a new policy position in a debate with George Allen in the race for Virginia senate.

"I would be open to a proposal to have some minimum tax level for everyone," said Kaine today at a Senate debate between himself and his opponent, Republican George Allen.

Allen said after the debate that the statement underscores Kaine’s desire to impose higher taxes on struggling, working-class Virginians. Kaine scoffed, calling it no big deal.
