Well, somebody seems to keep electing the clowns. Or the local constituients are failing to keep the elections (primary as well as general) fairly honest.
It’s not an exclusive “Or.” Actually its a both and. We would still get a lot of feckless bastards. Just maybe not quite so many. Get rid of cross-over primaries, get rid of ranked choice and go to paper ballots, in person with ID against vetted voter rolls and it might help. Of course a lot of dead and illegal voters would be denied their constitutional rights.
