Top Huntsman adviser dishes on Romney, Pawlenty

Veteran GOP strategist John Weaver took on two of his party's top presidential contenders, suggesting Mitt Romney's a political shape-shifter and calling Tim Pawlenty a "nice guy" who "pretend[s] that he's angry."

Weaver, who's helping to lead former Ambassador to China Jon Huntsman's (R) presidential campaign, dished on Romney and Pawlenty, two of the candidates who pose the biggest obstacle to Huntsman's bid for the Republican nomination.
