For all its flaws, the GOP remains the only vehicle for advancing conservative ideas in practice, and it is the only possible vehicle for saving this country from the truly awful consequences of Democratic governance. If the Republican Party loses all purchase with voters, Democrats will do to America what they've done to Detroit, Philadelphia, and Chicago. The health of conservatism cannot be decoupled from the standing of the Republican Party, and it is not too much to say that the welfare of the nation depends upon the Republicans gaining ground electorally. It is therefore self-indulgent and even irresponsible to say, "I'm a conservative, but I'm not a Republican."
