How the region voted

This map sums up how voters cast their ballots in more than 1,500 precincts in 17 counties. The turnout of 2.4 million voters was down by 6.5 percent in unofficial results compared with 2008, but President Obama (D) still carried more than three-quarters of the precincts. While most Maryland and Virginia counties voted more for Mitt Romney (R), the number of votes cast in the metropolitan area were enough to tilt the overall results in Obama’s favor.
