Trump will retain political legitimacy after he is removed from office. He will likely have a 'shadow cabinet' and will retain political sway over republicans and media discussions. It is likely that the media will not be able to stop talking about him as it is their obsession. This coupled with the fact that he can run in 2024 ensures that he doesnt just get lost in the background like past presidents have when they leave office. He will retain amazing support from his base and will have much influence. So even though he will lack legal legitimacy, he will retain his political legitimacy and it will shine through. The only way he lacked legimacy, is personally in your own heart and mind. But please don't let me stop you from trying to remind him every day that you feel he lacks legitimacy. As I said before, this obsession will be, in part what gives him the power he needs to invade discussion and remain relevant and unforgotten.
