The US has approximately 246,000,000 adults. The difference in the popular vote was roughly 200,000 votes, which is less than 0.1% of adults. For all practical purposes, the popular vote was a tie in the grand scheme of things. To say that Trump did not appeal to the majority of people is just an asinine fallacy.
The person that did not appeal to the people was Hillary Clinton. Trump flipped states that were supposed to go to Hillary. FL, NC, OH, PA, MI, WI. You don't do that unless you appeal to the people.
