The Role of Redistricting and Gerrymandering in Electoral Geography
Quick fact
In 2012, Democrats won the national popular vote for the House but Republicans gained a 33-seat majority, partly due to gerrymandered district boundaries that concentrated Democratic voters in few districts and spread Republicans across many.
Why this is interesting
During the 2012 U.S. House elections, Democrats won about 1.4 million more votes nationwide, yet Republicans won a 33-seat majority. How can a minority of votes control a majority of seats?
