The main argument against making mandatory tests or additional subjective criteria, is introducing gatekeeping into the election. Who approves the clearance? Who double checks it? Who do they report to? Are you going to trust the current administration when they say that someone doesn’t have clearance and can’t run? The system is set up so that the people are in charge of the government, and not the government being in charge of the government. The issue that we are running into though is when the people are absolute morons.
