Yep, writing-in non candidates is an exercise in futility.
It will make you feel good but that’s about it.
Most places, such ballots will go into the trash, and all down-ballot votes will be uncounted.
Is that helpful, do you think?
It’s the responsibility of individual voters to first verify the validity of write-in votes with their own County recorder.
I’d never risk my ballot’s destruction by a faulty write-in vote.
