Okay, Google . . . this is darn cool.

The map initially shows loads with states shaded according to one of the sources’ ratings of the Senate race; click the links on the left to switch to House or Governor races, or to switch sources. To compare the ratings head-to-head, click a given state or district, and you’ll see ratings from each source displayed. We refresh the data daily based on the latest ratings, so come back as the races develop.

If your map just keeps getting redder and redder, it doesn’t necessarily mean it’s broken.
