"Without real opposition, the wingers go from strength to strength. Under their influence, we’ve had a primary campaign that isn’t really an argument about issues. It’s a series of heresy trials in which each of the candidates accuse the others of tribal impurity. Two kinds of candidates emerge from this process: first, those who are forceful but outside the mainstream; second, those who started out mainstream but look weak and unprincipled because they have spent so much time genuflecting before those who despise them."
