There's no way around this; if it's gotten to that point of illness it has already proved itself extraordinarily weak. Blaming Trump for pushing it over the edge is just a politically-convenient privileging of the numerous other forces that must be pushing it over, and it's hard for me to believe that Trump is even in the top 10 reasons, especially given the lateness of his entry on the scene. Do we seriously believe that things would be so much better if Trump had not won? It's not like Obama particularly managed to hold it together or anything.
