Okay. Let's take a deep breath here.

I too have a tendency for worst case scenarios, but the one below is VERY unlikely.

Was just talking it through last night with a colleague.

I'll explain... https://twitter.com/toddgitlin/status/1285619714551689216

Actually interfering with people's right to vote by placing unidentified federal agents at polling places enough to sway the election is logistically and legally infeasible.

Unlike the protection of federal property, the feds have no authority over most polling locations.

But even assuming they ignored the authority question and tried to post up at polling locations to shut them down or intimidate voters
a) it's clearly a violation of the law;
b) they don't have sufficient manpower to interfere at all the voting locations they'd need to target.

Intimidating voters at the polls, that's some banana republic shit right there.

It's the kind of thing that we decry when it happens in other countries, and is a sign that a country no longer has free and fair elections.

It would be the end of America as a democracy.

Further, I don't think the can interfere with the counting and tabulation because of the ways those are counted, and handled at the state and local level.

I don't think even Barr would go that far as to intervene where it would result in a lack of free and fair election.

And it I don't think the GOP Governors and most Senators would go along with a lack of free and fair elections.

I DO have many other nightmare scenarios where Trump exercises autocratic tendencies.

Just not this one.

Side note, I studied @toddgitlin when I was an undergrad. Didn't know he was on twitter.
