You mean the guy who won the only contest that anyone was trying to win? You can complain that San Francisco would have won the Super Bowl if field goals were only two points but we have no idea who would have won under different rules.

Trump won the vote that determines who represents the people in the federal government. There was no other vote. You can add up the individual state votes, but that is a meaningless number because nobody is trying to win that. Fun fact: Trump also would’ve won under the rules used by most other advanced democracies for selecting the executive, because his party won both the most seats and the most absolute votes in the House. But that counterfactual also is irrelevant.
