We all know that primary races don't see a whole lot of turnout. But it's still always shocking to see exactly how few people end up making decisions for the rest of the population. Take Tuesday's upset in Virginia's 7th Congressional District, in which Dave Brat beat House Majority Leader (for now) Eric Cantor (R). A total of 65,000 people went to the polls, more than Cantor's campaign was expecting. But in a district that has 738,000 residents (according to the Census Bureau), that's only 8.8 percent of the population represented. And Brat only got a little over half of that vote.
