Apparently, Sarah Palin will resign the Alaska governorship in a few weeks, and her Lieutenant Governor will be inaugurated on July 25.  As yet, there's no explanation for why she's doing this, which, frankly, seems plum crazy.  I can't decide if it's worse for her politically if there's a real reason--a family illness, a pending indictment, whatever--or if there's none at all.

Update: Video's below.  Looks like the answer is "none at all."  And she looks EXTREMELY rattled.
