You know. I’m start to think that we really over analyze everything. We need most personable/attractive candidate. This is the case for most of the presidential elections in the TV age. A conservative will win when they can clearly present their ideas with a smile.
That's a BIG part of it, but not all.
Gov. Palin still rates unfavorably among independents, so some substance is needed, too.
But yes, "celebrity" is the main thing.
