not talking about illiteracy, ~50% of americans read at a 6th grade level or below... that's certainly enough to make an impact, the 2024 election was decided by ~250k votes across 3 states... Michigan specifically has a reading level below national average

And the percent of eligible citizens who vote is often not much more than 50% in presidential election years (higher recently but not for good reasons). It's even lower in mid-term years. If you're not an engaged, informed person and your worldview is based on USA Today headlines I'd rather you didn't vote.
