Either this is really cool, or I'm really nerdy. Probably both.
This site features an interactive map of electoral votes by state. Hovering over any given state gives you the percentages for each candidate, as well as the results from the last four presidential elections. There are several other features, including my favorite: "This Day in 2004." I could watch Virginia going from dark red (Strong GOP) to outlined in blue (Barely Dem) all day long. You can see a map of the Senate races and get details on top-priority House races. There's even some information regarding issues we've been paying attention to - like the bailout bill - and issues we haven't - like the fact that there are three liberal(ish) Supreme Court Justices who may want to retire soon.
