Biden currently leads in polls by more than Clinton ever did, but there is a path for Trump that doesn't involve the above:

1) Trump narrows the lead by a few points from about 10 points nationally to about 6 points nationally
2) The polls are about as wrong in swing states as they were in 2016 (while they were nationally pretty accurate, they were off by about 5 points in PA and MI and about 7 points in Wisconsin).
3) Trump again wins a majority of the electoral college despite losing the popular vote.

There's also this possibility. Trump campaign discussing plans to appoint its own state electors, no matter the results: report
