I speak only from my own experience. I did make an effort to vote in person, on Election Day. The people I saw at the polls (our county still has the stupid COVID-19-inspired "accessible voting locations" which are few and far between, instead of the old polling stations open every few blocks) seemed to be largely 50+ in age. I wish I could have had a better finger on the pulse of my precinct.
We need to have clean elections or we have no country. It’s that simple.
