While you may think that about [Huntsman], when compared to [Mitt Romney?], he has both a serious name and looks very intelligent and coherent.
My pet theory is that Huntsman is the Internet candidate like Ron Paul was before '08. Paul was then on the fringe of the Republican Party and had no chance in hell of winning, but found himself with a cadre of supporters. After the election he became chummy with the Tea Party types, and after 2010 found himself exponentially closer to power.
Huntsman is now on the fringe of the Republican Party and has no chance in hell of winning, but is finding himself with a cadre of supporters. Out of elected office, Huntsman cannot move closer to power like Paul, but he could be responsible for galvanizing another movement.
