Carter: Unity ticket would be 'worst of both worlds'

Former President Jimmy Carter only formally endorsed Barack Obama last night and he's already going off-message. He gave his opinion on the idea of a Clinton-Obama ticket in an interview with the Guardian today:

I think it would be the worst mistake that could be made. [...] If you take that 50% who just don't want to vote for Clinton and add it to whatever element there might be who don't think Obama is white enough or old enough or experienced enough or because he's got a middle name that sounds Arab, you could have the worst of both worlds."

Somehow, I don't think we're going to be seeing Carter at many rallies this election.
