Rep. Barney Frank (D-Mass.) blasted the Log Cabin Republicans Wednesday night, saying the gay GOP organization goes by that name because “their role model is Uncle Tom.”

Frank, who is openly gay and the first member of Congress to marry someone of the same sex, told OutQ on SiriusXM radio he’s been “appalled” to see the Log Cabins continue to stand by the Republican Party “in the face of this worse and worse record on public policy…on our issues.”

“They’re willing to be accepted with no rights, no right to marry, no right to serve in the military, no right to be protected against hate crimes…20 years now I’ve been hearing why the Log Cabins are gonna make the Republicans better and they’ve been getting worse,” Frank said. “I now understand why they call themselves the Log Cabin Republicans: Their role model is Uncle Tom.”

On Tuesday, Democrats officially adopted a platform backing gay marriage. Frank, who is scheduled to address the Democratic National Convention Thursday night, said he and husband Jim Ready have been “greeted as heroes” in Charlotte, N.C.

“People are glad to be participating in what I believe is the beginning of the end of this prejudice,” Frank said. “Jim and I have been greeted as heroes. I walk along and people ask for a picture, and I say, ‘By the way, meet my husband.’ And they’re even more excited.”

Frank said his speech would focus on Republican presidential nominee Mitt Romney’s time as governor of Massacusetts, and “Mitt Romney” versus “Myth Romney.”

“There are two Romneys,” Frank said. “There’s Mitt Romney — who was a hum-drum governor of Massachusetts and not very successful with our economy. And then there’s Myth Romney — Myth Romney is kind of a superhero of job creation, he is a businessman — put him in charge and everything will hum.”

“I wish Myth Romney had been governor of Massachusetts,” Frank continued. “My state would have been a lot better off…instead we had Mitt Romney and I’m just going to have to contrast the reality and the myth.”
