I don't see it happening admittedly. But again, who else do they have they can look to as a senior figure?
Nobody. They've all either died, or lived long enough to embarrass themselves.
People like Newt, W, Romney and Dick Cheney have embarrassed themselves so much, they can't be used as examples of what the GOP should strive for. McCain is a mess. Boehner is a mess. Ryan is a mess. Everyone who could possibly command any sort of respect, or had some respect (like McCain), have thrown it all away by riding the crazy train.
Versus the Democrats who have Clinton (both of them), Biden, Obama, Kerry, and Carter who are huge, well known, well respected Democrats. And in the reserves they can pull out people like Pelosi and Gore who might be not as popular, but still people that everyone knows and most people respect. The number of well know, respected Democrats is high.
Obama is going to be out there campaigning for Democrats for 30+ years. The GOP in 30 years will have absolutely nobody who has been with the party and been so respected for that long.
