Is this "very real possibility" for the democRATS based on the polling and the cast of clowns they are running? Look how well they did in 2016 with that corrupt clown Hillary and polls that said she was a shoe-in at 98%.
There is also a very real possibility that Trump will trounce them again and continue as president into his 2nd term.
My money is on Trump.
Enough low information, free stuff, and/or fraudulent voters could easily sway the election for the democrats, no matter how clownish the candidate.
