If true, and he does this, then Hunstman has gone truly off his rocker.
OTOH, he was Obama's Ambassador to China, and if he were to get up there and talk about his experience in China and then say, that although he "likes" Barrack Obama, he will be endorsing and supporting Mitt Romney for president, it could have a wholly different effect.
...ok, read it now. Huntsman has not confirmed any of this and it's been a week since the report. The sources are unnamed (always leary of that), and Hunstman's daughter is apparently going public claiming it is all a lie.
So, I am unconvinced, and I will believe it when I see it, or Hunstman himself confirms it...in the mean time, he has not retracted his endorsement of Romney, and by the wording, it would be a hard one for him to do.
