In a remarkable feat of crowdsourcing, Swing State Project has published presidential election results for each of America’s 435 Congressional Districts.
The map below indicates the CD’s where Obama improved upon John Kerry’s performance by at least 9 points (there are 50 of these in total, and they are highlighted in green) — as well as those where his performance was worse than or equal to Kerry’s (53 districts, highlighted in red).
