The difference is that the MSM is by-passed, as opposed to their slavish support of FDR.
FDR only gave thirty Fireside Chats during his twelve years in office.
The MSM & most big city newspapers were in his hip pocket. The chats gave extra oomph to whatever legislation he was pushing at the time.
PDJT’s tweets (”Sooooooo unPresidential!” his critics wail) bypass every conceivable barrier to his speaking directly to the people. If Twitter shuts down his account, they will only be making his point. He’s probably already told Twitter execs to go ahead, make my day.
