trump is by no means delusional. He is being pursued in the courts for his business illegality and his presidential malfeasance. It is to his benefit to ‘run for the presidency’ so that he can then argue that all of his legal grifting is not prosecutorial bc he is president OR the only reason he is being prosecuted is bc the ‘Deep State’ is out to get him (yet again). This is not delusional - it is based in greed and fear for his free-range grifting lifestyle being ended/upended.
He is just hoping enough white supremacists back up his ‘delusion’ to make all of that ish happen.
