66% of eligible voters voted in the 2020 election. Almost half of those voted for Trump. That’s 33% of eligible American voters.
Also, not all Americans are eligible to vote: felons in certain States, non-registered adults, children, etc.
I may just be being pedantic but it annoys me when I see people claim that half of America supports Trump/fascism when it’s just not true. The number is probably closer to 28% of Americans.
