Joe Klein encounters it while road-tripping across the US:
I traveled through North Carolina and Virginia, both in areas of deep blue and crimson red, and it was clear neither side trusted the other very much. For the conservatives, the country had changed beyond their imagining; not just civil rights but gay rights (a contentious referendum recently banned gay marriage in North Carolina), and new ethnic groups that seemed foreign–the South Asians who all of a sudden seemed to run half the convenience stores, the Latinos who didn't seem to want to speak English. Why, even the President of the United States was something strange, neither black nor white. For liberals, it was all about intolerance. You couldn't have a half-decent conversation with these Tea Party people, they said. "My mouth is bloody," a woman from Smith Mountain Lake, Va., told me, "from biting my tongue all the time."
