Well, if they don't get the votes, they aren't going to enact anything, conservative or otherwise. And if the Democrats get the votes, we know nothing conservative is going to happen.
And so real conservatives are asked to compromise again and again with our votes so Republicans can get in and push their agenda. Tell me, say the Republicans con a few on the left, gain the votes they need on promises, that as 'conservatives', you think they wouldn't keep to the new constituency. Exactly how many times will they be able to con these moderates into voting for them if they never pass moderate agenda items? One or two times before these moderates got to the Democratic side?
And what happens to real conservatives that vote year after year for these compromisers all on the promise that one day we'll see a conservative agenda? Are we just supposed to keep voting Republican as the President signs CFR (which hasn't been overturned), the Patriot Act, calls for extension on AWB (and I don't care that it may never reach his desk, he called for it and a conservative wouldn't even call for it), give $15 billion for AIDS in Africa (more than Clinton suggested), and put another industry on the government dole for $2 billion to come up with a car that no one wants? Never mind this new foreign policy brought to us by the fine folks at PNAC
Oh, but it's all strategery. I forgot....
