Trump regularly misleads by claiming to be the most popular president in history by pointing to his higher vote tallies compared to prior GOP candidates. The fact is every presidential election will involve more votes for both winner and loser that are higher than their predecessors because the population has been increasing at a fairly rapid pace for literally centuries, which is how we got from 3m in 1776 to 336m today.
Trump increased his vote total by over 20%! The population increased by about 1.5%.
Saying that Trump's numbers increased because of population growth, is not correct. It's not even close.
