Unfortunately Chip I see this as working against McCain. I think most conservatives biggest argument against Obama (besides his extreme liberalism) is his lack of experience. I think Obama's camp (once the initial shock wears off) shouldn't and won't argue that Palin is too inexperienced to be a heartbeat away from the Presidency. If the GOP starts going after Obama on the experience issue - the Dems would then hold the trump card. McCain and Co. just lost their most convincing argument on why Obama shouldn't be President - no experience!
