I don't know if Mitt Romney is better for the Republicans or not, but given his recent statements about Jeb, it appears that Mitt is all in on another run for the Big Chair and won't that just be a humorous little battle of the giant-headed, great-haired, middle-aged white guys (I have a 7 1/2 and I'm middle-aged, but have terrible hair, although I am still happy to have a full head of hair). I don't know if that's a recipe for Republican success or not.
I actually think if Hillary is the nominee, she'll likely win. She's able and there is the "first" factor she has going for her. Left-of-center though I may be (and firmly so), I'd almost rather vote for Rand Paul than Hillary. The country seems firmly stuck in a kind of terminal centrism where there is a massive disconnect between what people want and what they are willing to pay for. I think all an establishment candidate of either party accomplishes is pushing that disconnect down the road.
