Clinton V. Obama

The pressure of being second place must be getting to Barack Obama. Yesterday he broke the long-standing "no attack langauge" truce between himself and Hillary, saying, "The reason that this president has failed to lead this country is because he hasn't been able to unite our country. He's polarized us when he should have pulled us together. That's why the experience we need in the next president is the ability to bring this country together. It's not enough to just change parties."

Obama then referred to Clinton as "Bush-Cheney lite".

Clinton told CNN: "I've been called a lot of things in my life but I've never been called George Bush or Dick Cheney certainly. We have to ask what's ever happened to the politics of hope?"

Both candidates have posted the exchange on their sites.
