So now Lou Dobbs weighs a run for the Senate--as a stepping stone, mind you, to the presidency. Asked whether he had been urged to ponder a White House run, "Yes, is the answer," he said. Sarah Palin, far more likeable than Dobbs in my view, probably belongs in a similar category, though she is approaching it from the opposite direction: a politician burnishing her credentials as a celebrity, and making a ton of money in the process, rather than the other way round.

Sarah Palin would surely be better as a replacement for Oprah Winfrey than as president, and I say that not to belittle her: Oprah is an astonishing woman, a force of nature. But the point is, the fields are merging. Or I should say they continue to. Let us not forget Ronald Reagan, who did pretty well as president, considering.

Oprah should run for something. Al Franken has already broken through the Senate's glass ceiling for second-rate comedians. John Stewart, a first-rate comedian, should follow his example. And if the electorate hesitates, there is always the appointments process. I envisage Charlie Rose as secretary of state and Jim Cramer as Treasury secretary (a celebrity bloviator with money: perfect). Conan O'Brien? CIA director. Angelina Jolie, obviously, at the UN. And Lewis Black would be an outstanding Fed chairman.
