Various posters keep saying that Dean will start moving up in the tracking polls come Friday. They're wrong.
The reality is that we won't see a "Judy Bounce" from tonight until SATURDAY, as any polling done today will likely have been completed before the Sawyer interview. So, Friday will be another crater day, quite possibly, and Dean could conceivably start moving up on Saturday.
Will it be enough to overtake Kerry by Tuesday?
It may not matter. Dean's got his mojo back and a decent second-place finish keeps his hat in the ring --- enough to regain momentum a la Clinton in '92.
Ironically, the YEEAAAAAAAAAGHHHHHHH may have been the best thing that could have happened to Dean post-Iowa. It transformed him from a media curiosity to a pop culture phenomenon overnight... just like Clinton in '92.
