I highly doubt Trump thinks he's going to prison or is worried about going to prison, nor about Trump Tower being knocked down (I don't even know where that's coming from), and certainly not the fate of his children after his death. I just think he has too much ego to believe there will be consequences for his actions (he certainly doesn't think he deserves consequences, especially with the recent BS immunity ruling from SCOTUS), and he's too narcissistic to care about his actions affecting others.
I'm not really sure what issues they think he's gone soft on, pretty much his only policies the first time were "build the wall", "drain the swamp", and "lock her up". In 2020 I don't think the GOP even had a platform, it was just "Sleepy Joe" this and that. So are they mad he hasn't come up with a catchy enough insult for Harris yet? Do they just want him to play the old hits from before and tacitly admit that he didn't accomplish any of that when he held office before?
He didn't sell out, what changed is cognitive decline. He can't even stay on topic long enough to get a 3 word catchphrase going again. Someone should really see if he can repeat "person woman man camera TV" immediately after they say it to him, without him going on a tangential rant.
