A constitutional crisis would be a time when people dont know who the legitimate president is.We know who it is, but a great deal of propaganda to the contrary has about half of the public seriously in doubt.
You make an excellent point.
I would guess the previous president’s habit of ignoring the Constitution and laws in matters he didn’t agree with is a big factor.
Then using his pen and phone to legislate from the Oval Office had a lot more to do with about half the public not understanding we have a legitimate president now.
