Im not a fan of politics overall, its very often a waste of time and energy for those who cant avoid its power. Im more interested in natural dynamics, the people have to take some responsibility for whoever is voted in. So I would mostly be looking at Trump voters or people on the right and how possible is it they have enough regret to change a vote or not even that, just not vote Trump and vote nobody would be enough. I guess a couple could even vote Kayne though the story is more liberal voters will detract from Biden to Kayne. Some will say its impossible that Kayne means anything but at least one state maybe it tips the scales, I dont know but seems like this could be close enough of an election.
Right now I do think Biden wins because he isnt causing left wing voters to switch and apparently that happened with Hilary, maybe that story is wrong but seems to fit and who can really call the voters which can go either way in each election. Im convinced a fair few dont decide until the very day of the election vote and thats it they lick their finger walking up the steps to see which way the wind blows and decide thats the way to go on the day.
