There’s a good chance that Americans won’t know the winner of Tuesday’s presidential election while it's still Tuesday — or maybe even Wednesday.
Many states made it easier to request a mail ballot amid the coronavirus pandemic and concerns about crowded polling places.

As a result, it could take days to tally enough ballots to project a winner.
