Of course not all. But the US electorate as a body produced this decision. When your congress passes a law or your supreme court makes a decision do you not say that "the congress" passed a law or "the supreme court" made a judgement? I doubt you constantly say "a bit more than half the congress passed a law #notallcongresspeople".

Or, when, say France has an election, do you not say "the french elected Macron"? Or do you always nuance it by "this or that percentage of the french elected him"?

Nobody said ALL Americans chose this… But the majority did. He won the majority vote. America as a whole chose this. The first time around, you could argue that since the lost the popular vote by millions, that America didn’t choose him. But not this time. This time, America chose him and said it with their whole chest.

And sure, you could argue that “didn’t vote” actually won. But that’s still on the American public for refusing to actually get to the polls. If they cared enough to avoid it, they would have voted instead of staying home. But they didn’t care, and their non-vote said “I’m okay with either side. Doesn’t matter to me.”
