The losing Presidential candidate since the 2000 race has gotten on average 224.6 Electoral Votes and 47.56% of the vote.
The biggest loser was McCain in 2008 who received just 45.7% of the vote and a mere 173 electoral votes. A true blowout – the only candidate to lose with under 200 electoral votes and under 47% of the vote.

Regardless of who wins its an almost certainty that Biden/Harris will win the popular vote as the Democrats did in 2000 and 2016.
If you assume the polls are accurate Trump will do worse then a loser like McCain on vote % but not necessarily on electoral college votes.
Again assume the polls are accurate – does Trump get less than 45% of the vote and more than 200 electoral votes or less?
Only time and 79 days of hell after November 3rd will tell.
