A growing number of Republicans are expressing concern about Sarah Palin's uneven -- and sometimes downright awkward -- performances in her limited media appearances.

Conservative columnists Kathleen Parker, a former Palin supporter, says the vice presidential nominee should step aside. Kathryn Jean Lopez, writing on the conservative National Review, says "that's not a crazy suggestion" and that "something's gotta change."

Tony Fabrizio, a GOP strategist, says Palin's recent CBS appearance isn't disqualifying but is certainly alarming. "You can't continue to have interviews like that and not take on water."
