You might have heard about what New York City Mayor Michael Bloomberg calls the "terror gap"—that is, the legal loophole that allows people on the government's terrorist watch list to purchase guns and explosives.

But have you heard what Republicans say when, caught between the NRA and national security, they pick the former?

There's a good roundup here, and it's quite interesting. Take Senator Lindsay Graham (R-South Carolina), who, at a hearing today on a bill to close the "terror gap," described how he's so tough on terror that he wants to do away with Miranda rights for suspected terrorists—but also wants to protect the right of terror watch list denizens to purchase firearms.

Graham described the bill as an instrument of those who would ban guns altogether. "We're talking about a constitutional right here," he said.

Got that? We're talking about a constitutional right! But only one. Not all the others.
