This article was written by John Ellis, who is Jeb Bush's first cousin. He does not seem to favor Palin and his last sentence in which he suggests that her nomination would generate a third party and that "President Obama is not doomed" is a veiled threat that the Establishment may try, as they tired to do in 1980 with John Anderson, to split the anti-Obama vote and reelect him. But Ellis clearly recognizes that she IS the frontrunner and that, barring something completely unforeseen, she will be the GOP nominee in 2012.
Didn't work then. Even less likely to work now. If Jeb wants to take her on, then bring it on. Reagan beat Jeb's daddy. She can certainly put the wood to him if he is up for it.
The Bushes have helped to run the country into the ditch and gave us Obama and Clinton as their legacies. As Rocky told Clubber Lang, "Go for it."
