“all honest rats”
No such creature.
There are rats though, that are robots and vote generationally rat, not paying any attention to goings on, just swallow the Pablum on the tube nightly before dinner or their favorite propaganda sitcom.
They are not purposefully evil, just ignorant.
They are one mugging before seeing the light, and if they do get the scales lifted, some actually become fervent supporters of conservatism, albeit slow initially.
Likely they don't even vote personally, but they do hand in their ballots to the harvester, who then dutifully checks for proper vote, or replaces the ballot in the envelope.
True libs? screw em, may they rot in hell.
