The problem with Palin on a national ticket is not her lack of experience, per se. Few governors have much, if any, direct foreign policy experience, and we elect them President quite often. Specific experience can be quite overrated, and if you blindly use it to reinforce rather than challenge your prior beliefs and prejudices it can be downright harmful. The problem is that it isn't clear that she even pays much attention to the newspapers or has had, prior to this week's airplane flight to Alaska with McCain staffers, any in-depth conversations or even in-depth thoughts about the critical issues that have faced the country over the last several years. The Palin interviews with Charlie Gibson over the past two days have provided definitive proof that she lacks the intellectual heft that she will sorely need if she ever were to find herself having to weigh and choose between competing arguments made by advisors about complicated policy questions.
She's in way over her head. Worse, if you believe what she told Gibson about her lack of hesitation when McCain offered her the position, she doesn't even know it.
Add in McCain morphing from someone I once considered voting for to someone who flat-out lies, and I just donated money to a politician for the first time in my life.
