One of my faves I've seen tonight, it tells a lot of info with a simple, easy to read graphic. It doesn't hurt that I like the data too and not just the visualization.

Geographic map of Iowa, counties outlined with vector lines showing whether a county has shifted Democrat (blue vector points left) or Republican (red vector points right). The length of the vector indicates how much the county has shifted.
