Mental Health Screening For Presidential Candidates

I wonder if we've reached the point where mental health screening of presidential candidates is in order and necessary? I mean think about it. We screen and check people for all sorts of occupations. Usually because we're concerned about the protection of vulnerable people - our kids and grandchildren for example or perhaps people with disabilities or the elderly.

Well, here we are in the process of giving a person a job where they will be responsible for the young, the old, people with disabilities, and by the way, all of us. Responsible to the point of our survival. Seems like a pretty big deal.

So what kind of screening do we have in place to make sure we aren't electing someone who shouldn't have access to nuclear weapon codes? Hmm? Maybe there are previous occupants of the White House who wouldn't pass the muster? Lots to think about.
