United States Presidents Acquire a Staff Infection

This is a pun. The staph indicated by "staff" is staphylococcus aureus, which is the cause of staph infection. A staff infection is when the people you concede to including on your cabinet as President of the United States for securing votes and campaign contributions represent entrenched special interests that have been occupying cabinets since cabinets have existed. And over time those cabinet positions have been verily guaranteed as a formality of being allowed to state one's desire to run publicly and most of all legitimately.
