How many polling stations are there in solidly blue areas?

If I needed to intimidate people into not voting but I only had 30,000 brownshirts I would just be very selective about where I send them, where they'll have the most impact. Sending one anywhere isn't going to do anything, it needs to be a large visible presence in order to more effectively spread that fear.

I bet 30,000 ICE agents at the "15 or so" places where Trump needs a better handle on the voting would be enough to change people's minds about being there. Or maybe even stir up the base to have them come out and "help" the ICE army "monitor" the process. It feels like anything is on the table at this point.

The don't need to send them to all polling stations to make a significant impact.

You could very very easily steal an election by sending 10 armed gestapo to 3000 voting locations.

I imagine for a lot of people hearing there might be ICE agents at the polling stations is enough to scare them into not going

They'll just recruit more till the election. With the economy in shambles and people getting laid off everywhere, there are enough people looking for a job, even if it means working for ICE.

They're only going to areas Democrats might win.

They do not need to send anyone to the areas they know they win. You know, because a ton still votes for them.
