The historical average of those who don't vote is 45% in presidential elections and 60% in midterms. 38% VAP didn't not vote in 2020, 45.2% didn't vote in 2016 and 46.2% failed to vote in 2012. Midterms 50% didn't vote in 2018, 62% didn't vote in 2014 and 59% failed to vote in 2010.
The lowest turnout for a recent presidential election was 49% in 1996, that was the lowest since 1924 when 48.8% showed up to vote. The highest recent turnout was the 62% VAP, you have to go back to 1960 to top that when 62.8% turned out to vote in the presidential election.
Here on this we are political or at least pay attention to politics, I'd say half of all Americans don't except in a presidential election. Since the historical average for midterms is 40%, that to me is 3/5th of Americans don't pay any attention to congress either. At least not enough to care to vote.
