No dumb idiot can become the President of the USA. It takes something special. Tens of thousands of governers, senators, congressmen/women who were/are already successful politicians have tried and failed since the USA came to being.
Only 45 have succeeded and the fact that Trump got the job with ZERO experience as a politician makes his abilities all the more admirable.
Of course, you can just blame bats or other wild animals if it means that the Chicoms can hide their biological weapons plans, and thus not needing to pay compensation to other affected countries.
