Yes, but for real? There isn't a single Harris voter in that county? That's hard to believe.

Yes. This is East Ramapo. What you say is true. However, even taking that into account, there is even more irregularity.

In a given population, you’re always going to have outliers. No population is THAT hermetically sealed.

• Disproportionally low votes for Harris, combined with normal spreads for other reps and elections? Funky, maybe worth looking at, but not a smoking gun.
• ZERO votes for Harris, combined with normal spreads for other reps and elections? That right there is a fucking HUGE smoking gun. That simply doesn’t happen in electoral statistics. It’s effectively impossible.
