In a "Mitt Gets Worse" video released Tuesday, Democratic Rep. Barney Frank of Massachusetts blasted the Log Cabin Republicans for endorsing Republican candidate Mitt Romney for president.

"It makes no sense to argue, as some in Log Cabin do, that they will be advancing LGBT rights by voting or supporting Romney," the openly-gay congressman said. "We have never in American history had a sharper distinction between a very supportive candidate and one that's very, very opposed."

The Courage Campaign and the super PAC American Bridge 21st Century joined forces to produce the “Mitt Gets Worse” campaign. The multimedia initiative seeks to warn LGBT Americans about the dangers a Romney administration could pose for them and their families.

"I can understand them saying other issues are more important," Frank added. "Don't tell me that you are helping LGBT rights."

The Log Cabin Republicans endorsed Romney for president on Tuesday, saying "we believe Governor Romney will make cutting spending and job creation his priorities, and, as his record as Governor of Massachusetts suggests, will not waste his precious time in office with legislative attacks on LGBT Americans."

Frank has been engaged in an ongoing feud with the pro-LGBT Republican group, after he said their “role model is Uncle Tom” last month. The Log Cabin Republicans responded by saying Frank was trying to “divide, distract and deceive the American people.” The group said it was “a badge of honor” to be attacked by Frank, who they described as a “partisan hack” and the Democratic Party’s “attack dog.”
