Another way to test the question of whether voter ID requirements suppress turnout is to examine states that adopted ID laws after 2010. Did turnout in those states go down? Only two states with new ID laws also had competitive elections in both 2010 and 2014: Kansas and New Hampshire. Turnout increased in both: by one point in Kansas, and by more than nine points in New Hampshire. Looking across all 21 states with competitive elections, Maine had the highest turnout, with 63 percent. Maine has no ID requirement and allows voters to register on Election Day. But next up were states with ID laws: New Hampshire and Alaska -- though in Alaska, an election official can waive the requirement if he or she knows the voter.
