Have you bothered to consider your working hypothesis critically?
1) The hypothesized 1,000-to-1 can be done in several ways.
Stealthily, a few at a time.
All at once: bang stick
All at once: Earth shattering kaboom
A few at a time, it would be easier to blend in in an (sub)urban srea; these are more likely to be blue and (cinsequently) unarmed.
In rural areas, it’d take forever to kill 1,000, and if they try “roaming assassin” they’re more likely to be ID’d/boxed in: unless the co-opted police like the one in MD who lied about the bad guys being white males.
All at once: bang stick
Likely an urban area (population density) or sporting event/concert. Only takes out predominantly red voters if a country music concert like in Las Vegas: and the civilians rin away.
All at once:earth shattering kaboom
Gotta be an urban area due to population density, except for a Three Gorges Dam gives way scenario.
No guarantee of voting composition plus uncertainty of warning time.
Counterexample: the powers that be are extraordinarily stupid about evac, from Katrina to Maui. (Add in uncharged Teslas trying to evacuate, but those are almost all libs)
As I said, well planned, that’s what can happen. If communications are cut off, how are you going to know a couple hundred men are sweeping your town and eliminating the conservatives?
That’s what Roosevelt was afraid of when it came to the Japanese. He was afraid that Japanese, still loyal to the emperor, might launch suicide missions within America.
Does it need to be 1,000? No. Wouldn’t surgical attacks where 50 conservatives are eliminated in the stealth of night per attacker?
It doesn’t need to be rural. In America, in many places, the rural vote is an unimportant one as some counties or states have become urbanized enough that only the urban vote matters now.
It’s more likely, in this scenario, that purple counties would be targetted, because heavily conservative ones would probably preserve the conservative vote.
I don’t put anything passed those in power for what they are willing to do to subjugate America.
