Only Congress can change election day. Furthermore, if we don't have a clear winner from an election, Speaker of the House by default gets the job on January 20.
I haven't done the research as to accuracy of this, but a former US Senator
had a piece out a few weeks ago describing a (probably unlikely, but still unsettling) scenario whereby Trump loses the both the popular & electoral vote but still becomes the next president.
Skip to the numbered bits if you want the TLDR version, but the even more TLDR version is that there's a way to get the election determined by each
state delegation, and House Republicans currently have a narrow majority by that count.
Anarchism discussion
I suspect a good deal of this comes from many people thinking "anarchist = violent revolutionary and nothing else." Which then automatically lumps in anarchists with other open rebellion groups. Not trying to excuse it, of course, especially since few of those groups get this level of scrutiny - or are even working with police these days.
On another note, I had the opportunity/duty to read through the Republican liability bill and if I'm interpreting it right it's a frightfully horrible thing. The individual suits v. businesses for getting COVID is bad in a lot of ways, but the employment law schedule is kind of impressive - basically, if the company
holds a meeting to talk about how maybe they should do something about all those COVID safety precautions people are talking about, then employment law is 100% waived.
