Who's the local Republican with a seat/position at stake on the next ballot?

There's your party responsible for this literal "fake news" being posted to voters in order to intentionally mislead and interfere with an honest ballot.

Knowing the US, this probably isn't technically illegal and may even possibly be "protected free speech", even if distasteful and morally objectionable.

Sooner the whole fucking thing implodes the better, from an outsiders POV.

Election interference.
