Also note that The Donald may very well lead right after election day because 60 % of the Dems votes will be mail-in, while 60 % of the Repugs will be in person votes.
John Oliver had an excellent segment about it - conclusion being, that a final result may first come far into November...  Obviously Trump will use this to call himself the winner right away and if that doesn't fly, will do whatever it takes to kick out as many mail-in ballots as possible.

I wish you health and good luck in the coming civil war 😬
