On Morning Joe today, Jon Huntsman offered a variety of reasons for why his presidential bid failed, including this:
"A guy named Michael Moore who went on television and said 'That Huntsman guy. He's a Republican I think I could support' to be followed up by Jimmy Carter who said 'This Huntsman guy: I think he's somebody I could support' to be followed up by Bill Clinton, who went on television and said 'He seems pretty un-hidebound. He's a Republican I think I could' -- we were so toast in Iowa by then."
He also cited a late start, his refusal to sign pledges, and a difficult transition from ambassador to "politician."
