The DUmmies et al. are kinda wetting themselves over this. First they were giddy about this event -- now they are worried and think this is a Rovian trick designed to contine the storyline that Palin is being unfairly attacked.
As I have pointed out in the DUmmie FUnnies, DUmmies do not think, they merely react to stimuli based, with their reactions based on key "memes" developed over time. In this case, what we have are the following "memes" in play:
As seen by: a) someone hacks Palin's email; b) the DUmmies get in a tizzy waiting for the certain-to-be incriminating evidence to pour our; c) no such "evidence" is found. This leads to the next meme...
Refusing to even consider that their previous assumptions must be wrong, they immediately switch to the next autonomous responses, in this case, two different conspiracy plans, incompatible with each other, yet still both believed: a) The account was deleted before the "juicy" stuff was found, and b) This was all a red herring planted by Rove to garner sympathy for Palin.
Of course, the last part falls into another meme...
