One man one vote isn't a lie.
Popular vote would give all the power to New York and Cali. Is it really fair that New York City alone has more people than Louisiana, Mississippi and Alabama combined? It ensures that EVERYONE'S vote counts. Because when you vote like we do, you're voting against the other people in your state. You aren't voting against anyone in other states. So yea, one man one vote is absolutely true. But it doesn't cross state lines.
Trump didn't campaign to win the popular vote, he campaigned to win the electoral vote and win it he did, he whipped her ass.
