She is not going to run in this next election cycle, absolutely no way.
I don't see it, no, at least not for national office. The infrastructure isn't there. It doesn't mean that she can't influence who does, though.
I do note a couple of interesting things about the article: under a very thin veneer of "objective" analysis it gets the "Sarah is a quitter" meme out there at least twice. Crude propaganda can still be effective.
