Just adding: you'd want to believe that an important feature of having more than one political party in the country is that they would compete and keep each other honest, holding each other to account when wrongdoing is exposed. Colluding to prevent the other team from ever facing justice for their crimes reveals that in fact, both parties are hopelessly corrupt and are conspiring to keep their corrupt enterprise operating. It's quite perverse to claim that this outcome is the best that we could hope for.
