People interested in last-minute polling and early returns from today will be hard-pressed to find a better early-warning system than the diaries and the front-page posts at Daily Kos. People are constantly posting links to their tasty finds there.

If you find another good source for today's election returns, feel free to post it in the comments.

Update: PoliticalWire has some exit polls. Edwards seems to be winning SC and possibly OK. Interesting!
