The most compelling screening processes could occur at the federal level. Specifically, shouldn't anyone who wants to be president, and tasked with defending America, at least be able to qualify for a standard Department of Defense Secret or Top Secret security clearance? This is the one where they ask your references if you have any financial challenges or other difficulties that could make you vulnerable to being bribed or blackmailed. They also investigate and ask if you have contacts with any communist or subversive groups that advocate the overthrow of the United States. Clearly, if these tests were applied today, it is quite possible that neither Barack Obama nor Hillary Clinton would qualify for secret clearances, much less higher levels of Top Secret clearances.
