Youth voting is at its lowest point since it started being recorded. The US Census Bureau began recording the number of young people (aged 18-24) voting in 1964, when it was at 50.9%. In the last presidential election, the percentage of young voters had plummeted to 31%. The states that had a rise was those that had both a hot-button issue and a competitive statewide race. Two things that motivate young voters out of their seats.
