David Brooks latest article in the New York Times is mostly crap, but this part is worth reading:
This narrative happens to be mostly bogus at this point. Most professional conservatives are lifelong Washingtonians who live comfortably as organization heads, lobbyists and publicists. Their supposed heroism consists of living inside the large conservative cocoon and telling each other things they already agree with. But this embattled-movement mythology provides a rationale for crushing dissent, purging deviationists and enforcing doctrinal purity. It has allowed the old leaders to define who is a true conservative and who is not. It has enabled them to maintain control of (an ever more rigid) movement.
Remember: The biggest problem with conservative politicians is that they’re politicians.
