TPM has a story about Huntsman supposedly being over. Huntsman never was. The man has no constituency. There are no conservatives seriously for Huntsman, and Democrats have enough problems with centrist sentiment from Obama, they’re certainly not in the market for Jon Huntsman.
The only people in the Huntsman business is the media, specifically Matt Bai and the New York Times. Other than that, there is no Huntsman support. He’s their candidate, nobody else’s.
