### An Intuitive Congressional Race Barometer

Slate has a new infobox for Congressional races that clearly communicates potentially confusing layers of information in a wonderfully intuitive way. It showcases poll data (% likely to vote for candidate A/B) but also features an optional arrow noting the presence of a statistically meaningful trend (which could go towards any party) as well as a color bar representing the "lean" of the race, which simply designates whether the difference in percentages is significant when adjusted for the margin of error; a black bar is used instead of red, blue, or green (for independent - a category actually needed for the Lieberman vs. Lamont race) when the race is a toss-up.
