I can't disagree with that.  Right now, it's three dogs:
1) Mitt if you think we need a healer to deal with our polarized political environment.  It wouldn't be hard to argue the benefit.
2) Paul if you like the blow-things-up approach.  He may be too much change too fast, but it's hard to argue that his message is wrong.
3) Gingrich if you want a born-again conservative with Washington insider knowledge.  He's smart, but he lacks a filter on what comes out of his mouth.  He's also a great ideas guy, but great ideas guys always have to surround themselves with a lot of solid execution guys -- so where are his execution guys?
