That goes in cycles, too. The sharps who lead a party in its hour of triumph are roosters who think they made the sun rise. If you've ever been on a farm, here's the thing about roosters -- they're annoying because they keep on crowing long after sunrise. They're still Announcing Their Presence with Authority long after they're needed, and it's very difficult to restrain the instinct of throttling them.
Being a decorated veteran of the political wars is a sweet gig -- cocktail parties, talking engagements, book deals, and an endless conga line of starry-eyed Tracy Flicks (or for Republicans, rent boys presumably) just off the turnip truck. There is probably not one ex-advisor on either network or cable TV who knows anything about the future of politics, but because they all talk to each other they live forever in a self-reinforced world where the Southern Strategy and It's the Economy Stupid still matter. They are reliving their glory days.
Because of where we are in the cycle, right now there is probably no Republican over the age of 29 who will make a meaningful future contribution to electoral political strategy. The new sharps are already happily incubating away, but we won't know anything about them until their time comes in another decade or so.
