Markos Moulitsas Slams Chris Matthews On "Ed Show" (VIDEO)

Markos Moulitsas had strong words for Chris Matthews Friday night on "The Ed Show," slamming the "Hardball" host for his recent comments about the Netroots.

"I don't consider them Democrats," Matthews said of the far left, "I consider them Netroots. And if I see they vote in every election, or most elections, then I'll be worried. But I'm not sure they're regular, grown-up Democrats. I think a lot of these people are troublemakers who love to sit in the back seat and complain. They're not interested in governing this country. They never ran for office, they're not interested in working for someone in public office. They get their giggles out of sitting in the back seat and bitching."

Moulitsas, who founded Daily Kos and whose name has become synonymous with the Netroots, responded harshly.

"In 2003, when Bush landed his plane in the aircraft carrier, and spoke in front of the banner that said, 'Mission Accomplished,' Chris Matthews had an entire show based on that event," Moulitsas said. "And he said everybody knows that we won the war, except a few critics. Well, I was one of those few critics. People like me in the Netroots were some of those critics. And it turns out that we were right and the Beltway conventional wisdom was wrong. And once again, we're in a situation where people like Chris Matthews don't learn from these mistakes. They're trapped in this bubble and they think that they know better."

Moulitsas defended the political activities of his editors and readership, and ended with a threat for Matthews.

"If Chris Matthews is worried about us working, and if he thinks that we're not Democrats, then he really should be worried, because he's got a thing coming," Moulitsas said.
