Require Mandatory "mental fitness" and psychological testing to every presidential candidate to demonstrate not a danger

We are requesting that each person who secures a nomination or runs on a ticket for president of the United States be required to PASS a mental fitness psychological exam from at least two unbiased, board certified psychiatrist who specialize in dangerous psychological disorders that can not be cured with a pill or behavior modification, like serious personality disorders including anti-social personality disorder, narcissism disorder, borderline disorder. The reason is because many power hungry people fall into this dangerous mental category because their cunning and convincing skillsets, although dangerous, contribute to their climbing success and we don't want to get someone in the presidency who simply wants to "push the red button" as many lives are at stake.
