This is all Trump needs to say. For evidence he can cite literally hundreds of highly qualified, licensed medical doctors, including specialists in Neurology, Parkinson's disease, possibly degradation of the brain's blood supply. Forget personalities for the moment and focus on the fate of the country: Can we afford to vote for a fraudulently healthy candidate who cannot perform the basic duties of office?
That is the question a patriot must ask. As for politicians who are so power-greedy they can't ask the right question for the good of the country, they should never be considered anyway.
