Massie asks whether Huntsman is "running for the Vice-Presidency or as a marker for 2016":
Huntsman will continue to get a good press (hiring John Weaver, John McCain's image-guy/strategist was a smart move) and that press won't be enough. Nor will many people vote for Huntsman because of his foreign policy credentials: as Spencer Ackerman says, being a diplomat don't give you much suction or juice these days. Anyway, when the C-word comes up we know that Huntsman is going to say something sensible about how America shouldn't be too worried too soon by too much of anything that China might do. Most of the other "leading" contenders will advise Americans to press the panic button and this, I am afraid, will be more effective than anything Huntsman can say.
Chait is more blunt:
The posture of maximal opposition to Obama is the one single thing upon which the entire party agrees. The notion that a dissenter against that consensus might win the presidential nomination is not merely a longshot but totally absurd.
