Ordinarily, I would agree with you. But in this case, there was coordination between at least some of the Members and the angry crowd outside. Was every Member who voted against the certification intending to follow it up by working with the mob to intimidate everyone? No, but enough of them were to make the whole vote suspect.

Heck, they keep doing it. When their guy didn’t get the votes, they had angry mobs clog their phone lines and make threats. They try to get their way through brute force and intimidation. You can’t then make it all better by simply holding a coerced vote and saying democracy still functions.
