“Voters in 2018 who did not vote in 2016 were a small group (about 11% of all 2018 voters) but an important part of why the Democratic Party made gains. Among the 2016 nonvoters who voted in 2018, Democratic House candidates led Republican House candidates by a more than a two-to-one (68% to 29%) margin. Of everyone eligible by citizenship and age to vote in 2018, 44% voted in both the 2016 and 2018 elections; 36% voted in neither; 14% were drop-off voters (voting in 2016 but not in 2018) and a small share (6%) were new voters – voting in 2018 but not in 2016.” – Pew Research Center.
