Pollster Stanley Greenberg of Greenberg, Quinlan Rosner Research, asked voters to rate the leaders. Boehner has a 36 percent approval rating and McConnell is at an all-time low of 35 percent.

On the thermometer scale pollsters like to use, it wasn't better, with the two GOP leaders even trailing "GOP in Congress," Hillary Clinton and "Dems in Congress." For Boehner, the warm rating was 22, the cold 54. McConnell was worse, with an 18 on the warm rating.

"The Republican brand has become so toxic and increasingly toxic led by the leaders of the Congress," Greenberg said.
