WATCH: Eric Alterman on How Liberals Need to 'Toughen Up'

My conversation with Eric Alterman on last weekend's Moyers & Company continued even after the cameras were turned off -- the TV cameras, anyway. But we captured that extended conversation exclusively for In it, Alterman talks about Paul Ryan, Andrew Cuomo, liberals' weaknesses, and his dinner with then-Senator Barack Obama.

"The first thing we need to do, as liberals, to become credible to the other 80 percent of Americans who refuse to call themselves liberals, is find a way to make the government protection of their lives credible. And it's no easy task," says Alterman.
