Could Rep. Jason Chaffetz (R., Utah), a 43-year-old freshman, topple six-term Sen. Orrin Hatch (R., Utah) in 2012? Chaffetz tells National Review Online that he could and points to the recent ousting of Sen. Bob Bennett (R., Utah) by state GOP delegates as proof. “I’m not willing to shut the door on a potential Senate run,” he says. “I serve at the will of the delegates. If that’s what they want, then maybe I will.”
