This ad is a work of genius:

The Log Cabin Republicans support Rudy Giuliani, but they wisely say nothing of that in this ad.

They created the illusion of a positive ad (without scary music or unflattering still photos), while using clips of Romney that will absolutely annihilate him among the Republican base. Not only does it highlight his past support for Roe v Wade and keeping abortion safe and legal, in mentions his opposition to the NRA and even includes a clip of Romney saying, “I'm not trying to return to Reagan-Bush.”

Like I said, a work of genius.
