Thats quite literally false.

8% of registered voters didnt turn out. 28% of the population is not registered to vote.
Trump won 49.8% to Harris’ 48.3% which is a split of 316 to 226 electoral votes.

Your bad takes are exactly the unhelpful pretending that it was a clear cut victory that allows him to do whatever he wants that do not recognize that a lot of people are bot happy or ok with this.
Its easier to pretend everyone is sinple and evil than accept that there are no sinle answers. But you are unequivocally wrong to say that double the people support or helped Trump.
