FWIW, I believe the principle expressed at left is what will drive the 2020 presidential election. To wit, there must be 10 times more people who voted for Trump in 2016 voting for Biden this year than people crossing in the opposite direction.
Think about this. There are a lot of people who say, “Look, I made a mistake. I trusted Trump, but I’m certainly not going to do that twice. Now try to consider the mindset of a person that goes like this “Oh, I went Democrat in 2016, but now that I’ve seen what a competent and honest prince of a man Donald Trump is, he’s getting my vote, for sure!”
