It seems to me that if they introduce this bill to the Senate with a talking filibuster - before any government shutdown - that will put more pressure on the Democrats and make it harder for the filibuster to be successful.
In other words, if there is no urgent legislation being held up then there’s less pressure to end a talking filibuster, but if the filibuster is not only preventing a vote on the SAVE Act, but also on a vote to reopen DHS (which Includes FEMA) that is politically damaging to the Democrats and draws even greater attention to their unreasonable positions on the proof of citizenship and voter ID provisions of the act.
I think it passes. There’s just too much public sentiment for it. That said, never discount the GOPs ability to seize defeat from the jaws of victory.
