My understanding is that it doesn't matter whether they vote or not, or which way they vote. The Demos have the vote all locked up. They just need the bodies there for the headcount, to meet quorum requirements. If they can get them in the building, it doesn't matter what they do: sleep, eat, read, play board games. If they're present, quorum is achieved and the vote will go down.
Thanks for the reply. I wasn’t aware of the procedural rules for a quorum involved in this. Even so it seems strange that the Gov. would have the authority to send out the police to bring them back.
