Definitely a major contributor, but it's not just that. Trump is angry and that's appealing because we're all kinda angry too. A lot of us know that that anger is pointless right now and can only be used to make things worse, but it's still kind of a good feeling to see that reflected in someone in a position of power. If Biden had half that intensity, he'd have this in the bag and we wouldn't be talking about any of the other recent problems.
