From a friend of mine on FB (with a little editing for style):
In 2016 136.7 million voters showed up.
In 2020 155.5 million voters showed up.
Less than 19 million voters difference election to election.
In 2016 Trump got 62.984 million votes
In 2020 Trump got 74.223 million votes
Trump gained 11.239 million votes
In 2016 Hillary got 65.916 million votes
In 2020 Biden got 81.282 million votes
Biden got 15.66 million more votes than Hillary after not campaigning for weeks.
Weird math. 19 million added voters and 16 million of them are Democrats, even though Trump gained 11 million voters.
