Mental Health Testing for Presidential Candidates

As you may know, the US government administers mental health tests to individuals seeking high level government positions to ensure they are mentally fit to execute the duties of the office. However, the government does not screen potential candidates for the Office of President of the United States. In light of comments from recent presidential candidates that are racist, xenophobic, and isolationist we need to determine if candidates are mentally fit to hold the highest office in the land that controls the worlds largest military and an arsenal of thousands of nuclear weapons. The continued safety and prosperity of the United States is contingent on having a mentally qualified president and mandatory mental health testing needs to be a prerequisite for the Office of President.
