It's her divine mission, as she sees it. And it would be a function of "divine intervention" as she explicitly said last night.
Ambers, previously a skeptic, comes around. Given the complete lack of talent among GOP ranks and their universal fear of taking on Palin supporters, it seems obvious to me she will likely be the next GOP nominee. My hope, of course, is that this a) forces what was once a serious governing party to nominate a responsible fiscal conservative in the primaries and fight back against the madness; or b) drives every last sane conservative to realize they have no choice but to back Obama; or c) that Palin so alienates the GOP elites by primary challenges that they somehow manage to quash her and she runs as a "rogue" third party George Wallace style candidate, and helps re-elect Obama by an electoral college landslide.
This is so far into the future, of course, that it's pure speculation.
She may also implode as more scrutiny exposes who she and her dangerous, radical and clearly controlling husband really are. But I'm beginning to wonder if there's anything in her past, any lie or scandal, that could at this point deter her supporters. If she were found guilty of a Watergate-level iniquity, they'd see it as a frame-up by the liberal elites (as many, remember, did Nixon). And those elites, out of cowardice and fear, never nipped this in the bud when they could have; and that bitter old cynic, McCain, gave her the platform she needed.
So we have here a truly Coughlinite movement, headed by an Eva Peron figure, eager to use the Dolchstoss card to bring out the kind of voters Rove always believed could eventually crush even the most mobilized democratic GOTV operation.
