Have liberals found their combative new leader in … Keith Olbermann?

For years, some Democrats have been saying they need a feisty tea party-type wing of their own to motivate the base. But when former congressman Alan Grayson (D-Fla.) issued a news release comparing grass-roots Republicans to the Ku Klux Klan, for example, his own party accused him of going too far. Olbermann, though, told his keynote audience that it’s time to embrace just such tactics.

“We know that we must play by the rules that sicken us, against which our souls cry out,” he said. “We have to fight him on his own terms.”

Brock, who has said he wants to create a new “Breitbart of the left”-style media enterprise, couldn’t agree more.

“I think he can really be a critical voice of the opposition,” he said. “And he’s freed up to do it.”
