I’ve been poking around and reading procedural rules on this FISA bill. As near as I can tell because this is a conference report, it can’t be amended. It is sent to the floor of both Houses for an up or down vote. It can, apparently be filibustered in the Senate, but it cannot be changed.
Opponents need 41 votes to avoid cloture, and a lot of reading material. It’s time to see if a leader arises, but I’m not holding my breath.
