Joe Klein of Time magazine's In The Arena blog:

I saw a very effective anti-Ron Paul ad on the air last night, but I don’t know who was responsible for it. It was about gay marriage, which Paul tolerates because he doesn’t believe the state should involve itself in marriage. This is somewhat akin to supporting human sacrifice among the Christian Conservatives out here, and I suspect it will move some votes away from Paul over the next 24 hours.

The ad, of course, is by us.
