The anti-security theater alliance has always included right-wing and left-wing libertarians (both exist), ACLU-style liberals, limited-government-style conservatives, and however you would choose to classify the likes of Bruce Schneier or Jeffrey Goldberg (or me). I know of Republicans who, seemingly for partisan reasons like those Douthat lays out, have joined the anti-security theater chorus. For instance, former Sen. Rick Santorum. I don't know of a single Democrat or liberal who has peeled off and moved the opposite way just because Obama is in charge...So: it's nice and fair-sounding to say that the party-first principle applies to all sides in today's political debate. Like it would be nice and fair-sounding to say that Democrats and Republicans alike in Congress are contributing to obstructionism and party-bloc voting. Or that Fox News and NPR have equal-and-offsetting political agendas in covering the news. But it looks to me as if we're mostly talking about the way one side operates. Recognizing that is part of facing the reality of today's politics..
Yeah, much like a pay-freeze for government employees is "nice and fair-sounding."
