Okay, we're getting our first indication of what happened. It seems like a colossal sulk on Palin's part, or perhaps better to say an effort on her part to ingeniously combine anti-liberal media bias agitation with Christianist politics by portraying herself as having been crucified by the liberal media.

Said Palin, according to a reporter at the press conference, "You are naive if you don't see a full-court press on the national level, picking apart a good point guard."

More shortly.

3:52 PM ... So what happened exactly? As I just mentioned in our editorial chat, this clearly happened so quickly that Palin hasn't even had a chance to come up with a coherent cover story for her resignation. Some context is probably helpful here, however. Remember that based on the public record, Palin is a wildly unethical public official, guilty at a minimum of numerous instances of abusing her authority as governor. And a lot of very damaging information has come out about her in the last few days -- though mainly embarrassing information about her character rather than new evidence of bad acts. I would not be surprised if this latest round of revelations shook something else loose that we haven't heard about yet.

4:06 PM ... Wow. It just gets better and better. Apparently one of Palin's rationale's for resigning is that she would not stand by while so many taxpayer dollars were being spent investigating her. This from Politico has to be the best ...

Palin allies contend that her star power will still benefit her home state.

"She can be more of a help to Alaska from the outside now," said one Palin loyalist.

Now?

4:20 PM ... Hmmm. Even better. This is Gov. Palin's 'announcement', such as it is, on Twitter ...

We'll soon attach info on decision to not seek re-election... this is in Alaska's best interest, my family's happy... it is good, stay tuned

She apparently didn't realize she was resigning yet. Stuff obviously moving pretty quickly ...
