Limbaugh is to the Republican party what Jesse Jackson was to the Democratic party in the 1980s.

Rush knows what he is doing. The worse conservatives do, the more important Rush becomes as leader of the ardent remnant. The better conservatives succeed, the more we become a broad national governing coalition, the more Rush will be sidelined.

But do the rest of us understand what we are doing to ourselves by accepting this leadership? Rush is to the Republicanism of the 2000s what Jesse Jackson was to the Democratic party in the 1980s. He plays an important role in our coalition, and of course he and his supporters have to be treated with respect. But he cannot be allowed to be the public face of the enterprise – and we have to find ways of assuring the public that he is just one Republican voice among many, and very far from the most important.
