2. Love the results
It just goes to reason if Bush is stuck in the low to mid forties, his chances are very very slim.

3. Methodology?
I'm relatively new to your work (although I am also a electoral vote person) so if this has been asked, I apologize, but this board moves so fast, finding the answer to that would be VERY hard.

Particularly, what is the Win Potention (something like that, can't see that thread) variable, and how is it calculated.

Second, why the national data? It's sort of interesting, but irrelevant, unless we want to bitch and moan later that the popular vote loved us and the electoral college didn't. It seems to me that the state polls area all that matter.

Finally, I'd love to see the models that you are using for your analyses...I'm a poli-sci grad student...and am kind of fascinated by many of the calculations.
