In case you’re wondering about all this night stuff, here’s my understanding of it all from a few conversations with House folks today: Legislation can be placed on the “suspension calendar” as of Monday (can’t on Sunday). Leaders would prefer a voice vote for passing the Schiavo bill, but as we know, that’s not going to happen, members who object to the bill are either going to call for a quorum and (or) request a roll-call vote. Attendance is key: The bill on the suspension calendar can only pass if it has 2/3 of those voting and present voting yea. (If the roll-call vote is requested, as Barney Frank promised earlier it would be, at least 218 members need to be present and voting. 146 must vote year.) Sources tell me that the Senate is prepared to pass the House bill this time by unanimous consent. That gels with vibes Carl Levin was giving off on CNN earlier.)
