If Trump had gone golfing every waking minute for the last four years we'd have been far better off. Him actually doing things means he's doing bad things. The one single thing I might agree with him on--for different reasons probably--is that the tech visa industry is a mess and needs to be fixed. I reckon with him that's mainly "brown people coming here, bad".
Short of Biden keeling over, or Kanye West siphoning enough votes in places like Wisconsin, there is one way Trump can win: by getting enough rubes to believe there is a vaccine coming "really soon." You know it's coming, and he's already saying it (in a recent interview with Geraldo). Get ready, because anyone that kisses his ass or he can bribe or threaten is going to be saying it too. It'll be a great vaccine, ready "right after" the election, paid for by the Chinese, and as a bonus nobody else in the world will get it.
