If voters decide an elected official violated his oath of office then, in this case, it will be on the Senate to try and ignore the situation. So far, a Senator being drunk on the Senate floor is okay with the rest of the Senators as long he votes the agenda properly. A violation of oath is just a minor detail. Maybe a good rebuke would make it all go away.
Well, there is this unfortunate detail that a majority of the Senate voted for the bill in question.
So presumably you think a majority of the senators should vote to expel themselves. Not likely to happen.
