The republicans need to nominate a moderate.
Not going to happen during this ever lasting heatwave which has engulfed the Republican Party. No candidate that cannot survive in this warm climate, for example moderate Republicans (I think they're on the verge of extinction) will ever become king of the kingdom.
Anywho, I wouldn't be surprised if Governor Hunstman runs for the nomination in 2012 and ultimately loses the nomination to a conservative, think former Speaker of the House Newt Gingrich. Nor would I be surprised for that matter, if Governor Huntsman was selected as a running mate for a candidate along the lines of Newt.
