They may have marked Joe Biden on their ballots, but I still think he was an afterthought and the vast majority were voting against Donald Trump.
Vast majority may be a vast overstatement.
The Democrats have a large base of voters who will vote Democrat regardless of who is on the ballot. Pretty much an overwhelming majority of all minorities and recent naturalized immigrants as well as maybe up to 40% of Caucasian citizens.
There is always a squishy middle found in both parties who can break one way or the other. It all depends on how successful the programming and conditioning from the EIMC* was in inserting their code into the mind numbed robots and NPC's
