@Foofie,
In real life, the best solution is to abolish the job.
In industry when a job goes for 30 - 50 years and only attracts villains and jerks, the usual solution is to abolish the job. The only legitimate function of a US president is to preside over uses of the US military which do not rise to the level of a declaration of war and, for that, some other solution such as a council of house and senate leaders and the joint chiefs could be found.
Or, alternately, with the 17'th amendment rescinded, presidents could be selected by the US senate.
