Well, it’s an opportunity for the system to prove that it can prevent even a president with a large support base from making America fascist. I gather from your comment that you are pessimistic, but regardless of likelihoods, this is the kind of situation where checks and balances could prevent some very bad things from happening.
People are being disappeared, snatched up without being charged with a crime and being held in for profit prisons indefinitely. US citizens are being deported without even due process. Congress is feckless about it. The courts ask for the executive to please stop, but the executive branch is continuing to do the illegal things they've been told to stop doing.
Sure seems like these checks and balances are working out.
They are currently failing, yes. We can only hope that people look at the rest of the world and history, see how much worse it can get, and find their resolve.
The time for checks and balances working to save us has passed. There are mask wearing black shirts disappearing American citizens. The courts have ruled that “no, this isn’t allowed” and these rulings are ignored. Congress is impotent, and has been for years. There are no more checks and balances to deploy that might help.
We shall see.
