I don't think it's impossible for him to get his ass kicked. I think it's impossible for him to get his ass kicked by any of the other Republican candidates. Being the loudest candidate and using incendiary rhetoric doesn't actually make you conservative. Take Romney for example:
He was the governor of one of the most liberal states in the country Massachusetts. He introduced the predecessor to Obamacare, and he was pro-choice, pro-civil unions, and pro-cap and trade, but reversed all of these positions just in time for him to run for President in 2008. If you honestly believe this guy is an actual conservative, I have a bridge to sell you. Being respectful, diplomatic, and civil doesn't make you soft, and it doesn't make you liberal. It makes you a decent person.
Let's take a look at Huntsman's record:
He has an Ivy League education, and has served in every Republican administration since Reagan. He has real foreign policy credentials, something every other Republican candidate lacks. He is an actual conservative; he has always been unapologetically pro-life, he believes in the importance of the second amendment, and most importantly, he is more conservative fiscally than Romney could ever hope to be. He won both his elections for Governor of Utah by huge margins, and his approval rating topped 90% at several points. Utah is one of the most conservative states in the nation. Why would they so overwhelmingly approve of a candidate who is liberal and loves Obama?
Simply put, if you want electability, this is your guy. If you still think that Palin, Gingrich, Bachmann, or Santorum can win the nomination, much less the general, you are insane. If you think that Romney is more conservative than Huntsman, then you haven't done enough research.
