Legislative action will never bring genuine campaign-finance reform. Consultants will prove endlessly inventive in gaming whatever system the reformers can devise so as to give their candidate an edge and allow the power of massive money to be felt. But reform laws will become irrelevant and redundant as the Internet replaces the special-interest fat cats as the best way to raise money and takes the place of TV as the most effective way to get votes.

Rebut the negative, and the opposing campaign has not merely lost a skirmish, it has suffered almost irreparable damage. An effective rebuttal makes it hard for the campaign whose ad is destroyed to be believed about anything ever again.

In fighting scandal, the key is not to overreact.

Truth is that which cannot be proved false.

It is true that the top quintile is getting richer while the bottom is getting poorer, but the bottom is not the same people. There is, fortunately, a constant churning at the bottom as new immigrants move in and those who used to be on the bottom begin their long, thrilling upward climb to the American dream.

More and more, the Democrats are not merely inconsistent, wrong and/or misguided - they are the worst of all possible things you can be in Washington: irrelevant.

The most basic decision a modern politician must make is whether to be aggressive or conciliatory.
