As the 2018 primary season has rolled through the spring and summer, Democratic enthusiasm and turnout has been a dominant story in state after state, from New York to California. This week, the Pew Research Center put all those state-level stories into a national context with some eye-grabbing numbers.
The Pew analysis found that through June, 13.6 million people had voted in Democratic House primaries in 2018. The number was 7.4 million in 2014, the last midterm election. The 2018 figure represents an 84 percent increase over 2014.
The Republican House primary vote has climbed as well in 2018, but not by the same amount. CONT.
