When John McCain was in the Republican primary, he said Rudy Giuliani's eight years as mayor of New York City was not enough experience to be president. And, the four years that Mitt Romney was governor of Massachusetts was not enough experience. Sarah Barracuda has less experience than Giuliani and Romney had at their jobs. She was mayor of Wasilla, Alaska (it's laughable to even compare that with being mayor of NYC) for six years, two less than Giuliani, and has been governor of Alaska for less than two years, two less than Romney. But don't believe me, watch what McCain said from his own mouth.
The main point though isn't so much whether Palin is qualified or not qualified as it is the willingness of John McCain to say whatever it takes to get votes, even if what he says directly contradicts what he has said before, and his impulsiveness in selecting a running mate without adequate vetting. Truth doesn't matter to the McCain campaign. They have adopted Karl Rove tactics, whole hog (and you can't put lipstick on that pig.)
