Trump didn't even win 50% of the people who voted. He got the most votes (a plurality), but ~1.5% of the votes went to third party candidates, slightly more than the gap between Harris and Trump voters. One of the many reasons this "we have a huge mandate to reshape the country in the image of Project 2025" line is so infuriating; you have to go back to 1968 to find an election with a smaller non-negative popular vote margin of victory.

(Also, "non-negative" is carrying a lot of weight, since both Trump in his first term and George W. Bush in his first lost the popular vote. The idea that a wide majority of the country is conservative, let alone MAGA, is risible.)
