Maybe this will ease some minds. We've had mail in ballots for the first election ever. I would bet that most urban voters took that option over voting in person just to avoid the long ass lines. That means that most of the urban vote was counted before election day. Remember that a lot of urban areas were being rioted and that swayed a lot of undecided voters.The rest of the country is typically Republican. We are the ones that voted today. If the urban vote was even close, Trump's rural vote would put them over the top. That is why he was saying STAY IN LINE. We can win everyone cast their vote.
As an addition. All the early votes we are seeing are the mail in votes.
