You miss the context of the last sentence without reading the early part of the article I never posted.

The Democratic party has an obligation to beat the Republican party so badly, over and over again, that rationality once again becomes a quality to be desired. It must be done by persuading the country of this simple fact. It cannot be done by reasoning with the Republicans, because the next two generations of them are too far gone. The state legislators now passing all manner of crazy laws represent the next generation of national Republican leaders. They are proudly unknowing. They are certain, because it is impossible.
