House Majority Leader Eric Cantor's primary defeat was both stunning and convincing. Cantor lost by 11 points to college professor David Brat, a margin of just more than 7,000 votes out of 65,000 cast.
But, how exactly did he lose? This terrific map -- built by the awesome Darla Cameron with number crunching from Dan Keating -- shows how. Brat's win was comprehensive across the district but he walloped Cantor especially badly in the northern and eastern Richmond suburbs. Cantor's best showing was in Orange County, in the northern part of the 7th district, where he beat Brat 61 percent to 39 percent.
