Senators and congressmen cannot be recalled. This has been litigated in both federal court (Idaho, 1967) and state court (New Jersey, 2013). You’ll either have to wait for the Grim Reaper or his next election.
Unreal, so in essence you get slimebags like this guy run amok. There has to be something else that can be done though, maybe have him investigated. I can’t believe the people couldn’t rise up and drive him out of office. What about finding improprieties like taking bribes? This guy cannot be clean, no way. He’s a punk this guy and you usually find this kind of arrogance in crooks who get away with criminal activity for a long time, they think they’re untouchable and the public merely bugs for them to play with.
Senators cannot be impeached.
Dingy needs to be Censured then Expelled. He’d likely resign before facing Expulsion. All the better. It takes 2/3 of the Senate, I believe.
