More people (as a percentage of the eligible voting population) voted in 2016 than 2012, and more in 2020 than in 2016.
Finger wagging at people for criticizing the current ruling party (which is sending weapons to a country that is using them to commit genocide) instead of recognizing that we live in an undemocratic system is taking it out on the wrong people. Clinton literally won more votes in the election you're saying people didn't vote hard enough in. It's spitting in the face of everyone whose votes were shat on by the Electoral College to turn around and blame the people who were disenfranchised.
