From Andrew Sullivan's reader Dissent of the Day:
The key to Republican success in the last few decades has been getting people angry enough about crap issues like flag burning and gay marriage that they'll vote against their own economic interests. Now we're staring into the abyss, and one of the good things that's happening is that those largely irrelevant social issues don't have the punch they used to have. If a conservative is a liberal who's been mugged, a liberal is a conservative who's lost his health insurance. At that point, you don't really care that much who's sleeping with whom.
