Ask yourself: if Sarah Palin were not running for president, why on earth would she re-start her "he's an alien" bus tour in Iowa this week? Money quote:
A Gallup survey out Tuesday showed that Palin generates more enthusiasm among GOP voters than most of the candidates already in the race. And as Mississippi Gov. Haley Barbour recently put it, "she could raise enough money to burn a wet mule." … She has plans to return to the state over Labor Day weekend for a Tea Party rally in the Des Moines area.
The latter could be a perfect moment for a formal announcement. Yes, I know she could be squeezing the last drop of the publicity that will end abruptly the minute she says she's not running. And I can't know the future. All I can say is that everything I have ever learned about Palin suggests she will run. It's her divine destiny, as she and countless others believe. And if Rick Perry thought he could suddenly become the focus of attention in Iowa, he forgot someone as radical as he is, with more, er, starbursts.
