For Trump, starting a new party from scratch would be too much work, and would cut into his golf time. Besides, why would he need to do that, when the GOP has already morphed into the Trumpest Party, anyways? Donald can still rake it in, from both the cult, and the currently supine entity known as the former Republican Party.
These GOP types talking about Trump somehow stepping back, and enabling some form of "unity" are simply dreaming in technicolor. The Don can (and will) continue to get his attention, money and revenge....snug and cozy, within this absurd personalty cult, on an ongoing basis. Anyone in the GOP who is not a cultist, bigot, conspiracy theorist, or seditionist, better start making plans......
