The division was created by all the media (social included) manipulation of reality perception. I bet that in 2016 a much higher percentage of votes were against Hillary. In 2020 the "against" was very likely higher.
Division will likely keep increasing as everybody's media feeds become more and more tailored to the individual looking at them
Worth also pointing out that 4 years ago that social media was implicated as being manipulated by Russians.
Seems like no foreign state interfered this time around, but the point was that the Democrats blamed division on social media on the Russians and that most of us have amnesia about that.
