1. I can't verify this source but here is a report of 47 states and their status regarding mail in voting. NB The ones that don't are likely #RedStates in 2020. So it will impact other elections but failure of these state to produce electors to vote in December is bad for Trump.
2. My point in this is, add CO that was missing from this report and assume it's Blue, and we take back the three swing states that the GRU took for Trump, here is what the election would be if only mail in states voted. @JoeBiden gets an EC majority and therefor wins.
