Forcing the constituents to vote by mail is unconstitutional, along with the other bullshit.
FWIW, our asshole Dicktaster Wolf has mandated pretty much the same bullshit (dunno about the voting thing though) and the Supreme Court told him that what he has been doing is unconstitutional. I would very much like to see him hanging from a noose in the public square.
After the trial and conviction, of course.
