“It is facile and mistaken to attribute this particular madman’s act directly to Republicans or Tea Party members. But it is legitimate to hold Republicans and particularly their most virulent supporters in the media responsible for the gale of anger that has produced the vast majority of these threats, setting the nation on edge.

They seem to have persuaded many Americans that the government is not just misguided, but the enemy of the people.”
