He tried. There are books and interviews, available today, describing how unprepared he was (ie the basic housekeeping of staffing positions) to take his position as the head of the executive branch. He had no political infrastructure, which has been since remedied by some rather fringe conservatives (related to prj2025). He is unable to manage anything, ruling through typical narcissistic behavior of delegation and blame. He has a colorful history of exploiting legal loopholes. The only thing Trump consistently does, is prop up his own image and power to continue to operate in this manner.

This is not a compelling statement, in the slightest.
Again, this is one possible path for deconstructing American democracy, which easily sprung to mind and is dependent on his health in 4 years. Saying it's impossible, is another opinion.
