Sooner or later.
And she'll likely soon fade from Fox; Roger is said to have been tiring of her lately anyway. And, IMHO, we will have lost one of our brighter lights.
Perhaps that's what Sarah Palin wants. Lord knows I couldn't blame her. After the savaging she and her family took, with no one in the establishment GOP rising to her defense, I pray for peace and happiness for Palin and her family. But we've been diminished, and I for one will sorely miss her presence on the national stage. And if in November 2012, if the polling looks really good or really bad for the GOP nominee, I'll write her name in for President.
Naturally, if it's close, I'll cast my ballot for whatever also-ran the GOP puts up, knowing that all it'll acccomplish will be switching one set of cronies for another. I would have loved to vote for Sarah Palin; all I'm going to be able to do in 2012 is vote against Obama. Hopefully that will be enough.
