Well, let’s just hope that Romney doesn’t turn out to be another JFK. Not that Nixon was that great, either, having gifted us with the EPA.
Nowadays, JFK would be considered too far to the right to gain the blessings of the GOP-E. If that's the way Romney turns out, I'll be pleased beyond all expectations.
It's also less likely that Mitt would go chasing celebrity tail, so there's that.
