Today, a politician does not just need public support to win elections; he needs it to govern.

The cost of campaigning has skyrocketed in recent years because of the falloff in TV viewership. With only one-third as many people watching TV as did 20 years ago, politicians have responded by buying three times as many ads, driving the cost of campaigning to levels which only favored candidates can afford.

Socialist countries throughout the world love to lower retirement ages to make people prematurely dependent on the government. But we should move in the opposite direction. In the long run, indexing retirement to life expectancy will yield enormous revenues to the system, far more than a one-shot increase in the age in the current legislative cycle.

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

Any Democrat who squirms on the tax-cut issue in the primaries has no chance ' zero ' to win the nomination. Each will have to take the “pledge” to oppose the Bush tax cuts. Thus, Bush will have succeeded in creating a situation where anyone who can win the nomination can't win the election. Democrats are not about to nominate anyone who backs the tax cut, and Americans are not going to elect anyone who favors a tax increase.

Americans will gladly support their president when he attacks nations that sponsor or harbor terrorists. We will even back him in a preemptive war against a country that might attack us. But when we start sending troops around the world to stabilize nations that, if left to disintegrate, might become breeding grounds for terror, it's a step too far for most Americans.

The financial interdependence of the world's banks is like the interlocking alliances that predated World War I.
