They say that when you see one roach in the open, there's thousands of them hiding in the walls.
Because they're good at hiding I suppose.
The chances of seeing one individual roach in the open during it's short lifetime are extremely low because they stay in the dark. But when there are enough of them in one area, just due to the sheer numbers, eventually one or more of them is going to be spotted simply due to the laws of probability.
Same principle here with criminals tampering with elections (and thereby depriving Americans of the democracy the democrat party constantly claims everyone who disagrees with them a threat to

).
We all know which party is the one cheating in every election. It's the one that cannot even concoct a believable story for why they oppose any & all bills that would safeguard elections from fraud.
Democrats keep voter fraud so easy to perpetrate & get away with that the odds of catching them are slim.
When we catch one, we know there are orders of magnitude more of them to be found.
The democrat party represents & consists of criminals, illegal aliens, pedophiles, communists, most foreign adversaries, and they have convinced themselves & their flock of fools that the very basic concept of law is "fascist", (but only when they aren't in total control of it).
So a comparison to cockroaches is entirely appropriate. Today's marxist, anticapitalist democrats, hell-bent on seizing power through deception and fraud, are basically the cockroaches of mankind.
Somebody call the Orkin Man.
