Jack Kemp couldn't get over the top without having won a statewide race. I was surprised an ex-Mayor, even ex-NYC mayor, showed so well in the early polls, so I guess I'm not so surprised it looks like he's about through.
I'm sure a lot of liberal Republicans would like to through social conservatives under the bus, but it won't happen. The party has a three-legged base and removing one of the legs brings the stool down. Huckster is finding that out by trying to throw the pro-growth, pro-business people under the bus.
Repubs CANNOT win without so/cons. They know it. And we know it. Rooty's demise more than underlines this universally accepted political reality.
