John McCain's arguments against Obama's alleged "lack of experience" are moot with his selection of Sarah Palin. Who the hell is Sarah Palin and would America want her a failing McCain heartbeat away from the Presidency?
We can only surmise that McCain realized that he cannot win the experience argument against Obama and that he is instead strategically trying to peel away disaffected Hillary Clinton supporters from Obama. That assumes that those supporters only vote for candidates based on vagina verification and not because of their qualifications for the office. It also assumes that they need an older white male to ride in and save them from their loss, to fix everything.
But this is no fix. The answers to, "Who the hell is Sarah Palin": she's a former beauty pageant runner-up (that alone ought to satisfy feminists); she's been Governor for a small state for less than two years; before that, she was Mayor of a small town called Wasilla (pop. 5,000--ever heard of it?); she's also embroiled in a controversy over her firing of an Alaskan Public Safety Commissioner who refused to fire her brother-in-law during his bitter custody battle with Palin's sister. So, the answer to, "Would America want her a failing McCain heartbeat away from the Presidency?" ought to be a resounding "No!" regardless of Hillary Clinton's fortunes.
Wasilla is just too far outside of Washington to do us any good.
UPDATE: But Palin does have foreign policy experience. That is if by "experience" you mean her state sits next to Russia:
