I didn't get an email despite being "on the list" but checking the countdown today, looks like they're launching PAC, Peaceful American Constitutionalists. A movement of We the People taking action, peacefully mind you, and standing up to tyranny. I also noticed their street address, 1717 Penn. Ave.

Edit: So I've been doing some digging just to check things out being called out as a LARP in comments. This is what I have so far, C&P'd from my reply below:

Maybe, maybe not. Was just trying to do some research on the site. Waybackmachine has snapshots from 2018 & 2019 but just say "Please check back soon to see if the site is available." Really didn't start coming into play until 2021.

Who.is has it being registered on 1/12/20, although I suspect that's the current owner. It must have been registered previously for waybackmachine to have snapshots prior to 2020.

Also, the physical address on their site, is also the same address/suite number as https://www.patriotstrategies.com/

So, may or may not be a LARP, but definitely seems to be a gimmick, which isn't necessarily a bad thing...
