If you want to waste some time, the L.A. Times has the best interactive electoral vote map. You can see the results of past elections, play with various outcomes. Combined with Zogby's daily tracking polls you can play with all the possibilities. Honestly, though, there isn't that many possibilities. Ohio and Florida are huge. The map I included is admittedly the best-case scenario for Kerry, but one which I honestly think is a possibility.
I saw something interesting this morning on MSNBC - Joe Trippi was being interviewed and he said that Zogby has been conducting SMS-only polls in the past few days and determined that the youth vote favors Kerry by 15 points. Very interesting.
