The big issue is that she has absolutely no experience in national politics and has only been governor of Alaska for a year and a half. Basically McCain used his VP pick as a political stunt designed to steal coverage of Obama's acceptance speech. This is possibly the most short-sighted VP pick in history and in my view a colossal blunder by McCain. And since Eddie liked my line about how one should view Palin's "experience" in the executive branch in Alaska, I'll repeat it here:
Governing Alaska is like governing Sim City with the free money cheat. It’s easy to repeal taxes and fund infrastructure at the same time when you have a money spigot.
