Trump is not the same as he was in 2016, he's not mentally sharp

One of the many reasons he won the election that year is because he brought up a lot of strong arguments against Hillary that stuck. But now that Biden is the nominee and Harris is his pick for VP, the comments coming from Trump are: "Biden is a radical leftists, Harris is mean, Biden will take away religion, etc. a lot of very weak attacks that I assume it will get worse as time goes on. It's no secret that Republicans love to attack Biden on having a few loose screws, while ignoring that Trump is facing the same mental decline as well.
