The only drawback to the Palin selection is that it (to some degree) undercuts the inexperienced argument. While Palin certainly is more qualified than Obama, a superficial anlaysis of the age, time in government, etc won't help. And we know the MSM doesn't do anything deeper than the superficial.
One other drawback is that Alaska is already in the McCain camp, so it doesn't immediately flip a single state in McCain's favor.
However, here are a couple of points that will help McCain.
1) Palin favors drilling in ANWR and with gas prices as they are, this is a killer issue for the GOP. I can just imagine the exchange during the Vice President debates:
Biden: We can't drill in ANWR because of the environmental impact and because it won't have any impact on the price of gasoline until 10 years from now!
Palin: Senator Biden, with all due respect, the mere mentioning of the possibility of drilling offshore earlier this summer caused a $20/barrel drop in the price of oil. Using American energy resources instead of Saudi Arabian energy resources in the short term, while transitioning into a green-energy economy, sees like the best option.
And Senator, while you're commuting back & forth from DC to Delaware, I live in the state of Alaska. And if you think that you're more concerned about the environment of Alaska than someone who lives in Alaska, I think you've spent too many years in DC.
Senator - While you've "summered" in The Hamptons, I've actually vacationed with my family in ANWR.
She's not from D.C.
She has a maverick streak against the GOP pork-barrellers in Alaska.
All of this lines up with McCain's strengths.... Now, it's just a matter of communicating it to the voters.
The people over at Draft Sarah Palin have a lot more details.
