When Koya Graham turned 18, the first thing she did was register to vote. And, year after year, the Cleveland native faithfully voted for Democrats — that is, until the 2016 presidential election. "I'm not interested anymore," Graham told NPR in the Spring of 2016. "I don't see any immediate, significant changes happening." And Graham was not alone. It's been estimated that millions of people who voted for Barack Obama in 2012 stayed home in 2016.
