I was being a little bit facetious, if Trump runs and wins in 2024 there will no doubt be an enormous amount of angst on the Left and they will resist and obstruct every day of his presidency and no doubt file lawsuits aplenty to challenge the election results much like the repubs have done with the 2020 election. As is their right.
Would there be another Jan 6th type storming of the Capitol building? Riots in the streets of DC and around the country in democrat-held cities and states? Could be, it wouldn't surprise me at all. Would that be an insurrection? Absent weapons, probably not. There's a difference between a few hundred idiots and several thousand armed rebels, if that is the correct term. What exactly is 'full insurrection mode'?
Would I support martial law? I don't think Trump has that authority, much like he didn't when it came to the nightly riots during the summer of 2020 in our major cities. Maybe Congress could give the authority to declare martial law, but that would seem to be unlikely, and even that is uncertain. States can do it I think, and they can ask the federal gov't for troops to assist them in maintaining law and order, but if Trump was the president that would appear to be very unlikely. Ultimately, I think such a declaration would have to be under the direst of circumstances where a state governor basically has no other choice.
As far as the suspension of our constitutional rights, that's another story. Which rights are we talking about and for how long and how much? Within reason, yes I would comply. But if some fuckwad democrat governor wants to confiscate my guns under the guise of martial law then no, I would not support that. In the case of an insurrection, I'm not giving up my right to defend myself and my family and my home.
