Given that they'd find it all between the primary and the general election anyway, I think the opposite strategy is in order. Get that shit out into the open early, so you don't get blindsided (the way Palin was).
That would, indeed, be the intelligent way to do things. Dunno if they're going to play it smart.
(Point of order: Palin wasn't blindsided, SHE knew all the crap that was out there, if not that it would hit the papers. McCain and the GoP were the ones blindsided.)
Naw. The last election proved that they aren't capable of vetting, let alone keeping their fat mouths shut.
If we were dealing with rational humans, I'd say they'd learn from experience. We are, however, dealing with a party bowing to teabaggers, so... who knows.
