Rush Limbaugh killed the GOP

Good stuff from Ross Douthat.

From the link (and taken from the middle of a longer graf):

For Rush, there are only two kinds of people in Republican Party: True conservatives like him, and “moderate Republicans.” The latter is an ideologically-inclusive category: You can be pro-choice or pro-life, David Frum or Colin Powell, a Rockefeller Republican or a Sam’s Club conservative; indeed, the only real requirement for moderate-Republican status is the belief that the Republican Party needs to reach out to voters who don’t agree with, well, Rush Limbaugh on every jot and tittle of what conservatism is and ought to be.
