Take a look at Wayne LaPierre's statement. It isn't the socons who screwed the Party. The Party screwed them AND the libertarian fiscal conservatives. Bush and the hacks running the Party reneged on the Contract With America, which contained planks for both fiscal & social conservatives. For example, do you really think it's socons who wanted "public broadcasting" and the Dept. of Education saved? Was it socons who wanted Sandy Burglar let off the hook, and hobnobbed with the Clintons?
the contract with american contained proposals on abortion, gays, and guns?
The Fiscal Responsibility Act
The Taking Back Our Streets Act
The Personal Responsibility Act
The American Dream Restoration Act
The National Security Restoration Act
The "Common Sense" Legal Reform Act
The Job Creation and Wage Enhancement Act
The Citizen Legislature Act
The Family Reinforcement Act
The Senior Citizens Fairness Act
Now I will grant you that the Bush administration may have waffled on a few things.
But look at the list of issues above - the most vocal part of the base isn't interested in what the candidates have to say about them, they are second tier issues now. Look at the anti-Rudy threads here, all anyone wants to talk about are abortion, gays, he wears a dress, etc.
