I keep seeing on twitter that Trump has won Florida but Biden is still 100k up? Do they know something we don't know?
Postal and early voting favors Biden. So if these votes are counted before/on election day like in Florida the trend will shift to Trump as live in the day votes are counted during the day. When postal/early votes aren't counted until after the polls close the live/on election day votes come in first and the postal/early votes take longer to count, so things get better for Biden as the count goes on.
