Speaking of polls, this interactive chart on The Wall Street Journal is cool. You can see the trajectory of many different polls over time with key moments in the campaign overlayed on the chart. You can go nationally or state by state. I also like that by putting your cursor over a node you can see how many people were involved in the poll.
Click on the link above, and then when you see the electoral map, scroll down to the graphic shown at right on this page. Click that. Its beyond me why there isn’t an easier way to link directly to it, but I tried a bunch of things and they didn’t work.
UPDATE: WSJ gives an interesting discussion on why the polls might be wrong or at least off.
