CNN and Fox News both have up their websites where you can start tracking all state and localized races as results come in. MSNBC will likely have one at some point but, correct if I'm wrong, I don't see one up right now.

I still remember the CNN site from 2002 and I'm ecstatic it's still up. You can pretty much find out what any candidate had for breakfast this morning within about five clicks or so.

The live-updating result postings are also really fun to use because there will be no advance exit polling or statistical speculation. Take for example Florida's Senate race: Because the poll results have been embargoed, we will have no idea if Katherine Harris won the Senate race in Florida until the results are posted. I'm going to be on the edge of my seat watching the precincts trickle in. The online sites provide this service to us, and for that I am grateful.
