I think it was the votes of less than a third of eligible voters that made Trump 2.0 a reality, roughly another third just behind it, with the remainder not bothering to vote at all. I would say the often fantasized silent majority is actually not pro Trump.
That means that a third didn’t bother, though, despite Trump very much being a known quantity. The exact reason why they didn’t vote is up to debate and it’s probably several reasons at once (these people are not a monolith), but it doesn’t say any good things about them or the political system.
Yeah, that’s fair. They certainly don’t make it easy to vote in USA, which is deliberate to a large extent. Easy to forget.
