Nonsense. The GOP would never jump a shark. They’d see the shark and run away screaming and crying about how they’d just seen a shark. Then, they’d hide somewhere and try and come up with a plan to negotiate feeding themselves to the shark slowly, one body part at a time, so they got to live as long as possible. They’d do this in exchange for the shark promising to go away afterwards.
Actually, I think they would appoint a bi-partisan Commission on Sharks. Two years later, a report on sharks would be released with much hoopla.
