As much as I despise Carter, I think he's found some things to be right about here:

Hillary as Obama VP ‘Worst Mistake’

Naming Hillary Clinton as Barack Obama’s vice presidential running mate “would be the worst mistake that could be made,” said former President Jimmy Carter.
...............................
Carter cites opinion polls showing that half of U.S. voters have a negative view of Clinton.
...............................
After formally endorsing Obama for president Tuesday, Carter asserts Obama and Clinton together on the same ticket “would just accumulate the negative aspects of both candidates.”
...............................
“If you take that 50 percent 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,” Carter said.
...............................
His comments, it should be noted, came before Obama clinched enough of the Democratic delegates and superdelegates to win the nomination.
