You really don't expect a VP candidate to associate the Bush Doctrine with preemptive war, one of the greatest shifts of U.S. foreign policy of the last century? How can it "NEVER" be answered in an interview? "I'm sorry Charlie but you know me once I get started talking about the Bush Doctrine I just can't stop myself and it'll ruin the rest of the interview." I'm sure she'd have an answer about abortion or stem cell research. Aren't those complicated issues filled with gray areas and nuance?
