If that were true, she wold have won. What happened was that former Democrats crossed over and voted Trump and a large section of Democrats, pissed off at Bernie, stayed home. Republicans voted as usual thus tipping the unexpected win.
What happened is Trump awoke a sleeping giant ... Hillary was a dead candidate walking ... when she could stand up ... no energy ... no ideas ... and a detestable person.
Although I think Trump still has the edge, this year all of the Democrats are pissed off and will have a record turnout while more Republicans are disappointed in Trump blowing up the deficit and national debt...not to mention his loony ideas and fucking up the COVID-19 response.
You can run Uncle Joe on that platform if you want ... there aren't any more anti-Trump resistance neoprogs to attract with it ... you have them already.
Uncle Joe is not going to excite anyone to vote for him ... President Trump's supporters are chomping at the bit to vote.
