He's definitely changed and wasn't always coming off this way; although he may have always believed these things, he certainly kept it to himself more up until the end of last year, round about the end of Biden, the coming of donny scumbag 2.0 which is probably relevant.

I started calling him out on it somewhere around October or November last year and it's only accelerated since then. His ego is also taking a bruising and it's affecting him a lot I think.
