The Los Angeles Times has the story here:
"They are fired up. They are mobilized. They see an opportunity to take back the House, maybe take back the Senate," he said. "If they're successful in doing that, they've already said they're going to go back to the same policies that were in place during the Bush administration. That means that we are going to have just hand-to-hand combat up here on Capitol Hill."
Suddenly it's OK to use this kind of speech.
Just seven months ago Democrats were accusing Republicans of trying to foment physical violence over the passage of Obamacare because they used this kind of vivid language of "fighting." Within a week the FBI had raided the Hutaree militia in southeast Michigan and other states, accusing them of planning an armed revolt against the government. Google "Republicans threaten violence over healthcare" and see how many million results you get. It was an hysterical reaction designed to incite hysteria, and perhaps goad someone into making a mistake which would be very politically valuable to the Democrats.
This is the m/o of leftist extremism.
