While not all ballots have been counted, Democrats hold an edge over Republicans in overall votes. According to ThinkProgress, 53,952,240 votes were cast for Democratic candidates, while Republican candidates received 53,402,643. However, thanks in part to redistricting, Republicans will hold more than half the seats in the House while receiving less than half of overall votes.
In Pennsylvania, for example, President Barack Obama received 52 percent of the vote, compared with Mitt Romney's 46.8 percent total. However, Democrats won only five of the state's 18 seats in the House of Representatives. As Slate's Dave Weigel points out, the state's congressional districts have been gerrymandered to keep suburban and rural areas red. Ohio shows a similar trend, with just four of the state's 16 seats going blue.
After Tuesday's election, the House total for next term stands at 234 Republicans to 195 Democrats, with six races still uncalled. Democrats currently lead in five of those six races. If those five win, Democrats will have picked up a net gain of seven House seats.
