Mail-in voting became much more common in 2020 primaries as COVID-19 spread
Mail-in ballots accounted for just over half of this year’s primary votes cast in the 37 states (plus D.C.) for which data is available.
With less than three months until Election Day, Joe Biden has an advantage over Donald Trump among registered voters. But support for Trump is much stronger.
Just half of registered voters expect to know results within a day or two of Election Day, including nearly identical shares who support Trump and Biden.
