Taking this at face value... what exactly can a regular person do about this? A lot of congressmen already don't like what is going on. Complaining to them seems like preaching to the choir.
Get as many people as you can to go to their state capitals or nearest government building and camp out. If that doesnt work the founding fathers expected us to literally challenge the government by force ourselves. Hints the state's monopoly on violence.
Complaining to them is what they're there for. Make it clear to the ones who represent you that you demand action on this. That's the whole point of them having a job in the first place.
Beyond that, I would say what regular people can do is organize anarchically so that as the empire continues to collapse, we have structures in place.
Meet your neighbors and start thinking about how to exist without a state.

If if you actually believe this is a fascist coup, then why wouldn't they just write down your name and address and then come and shut you up later when they have more power?
