It means dumbass Reid actually does not know when the 14 senators will give up the senate floor.
Yep.
I think Reid is full of bluster. IIRC, the Senate recently changed the rule so that a motion to proceed to a bill can't be blocked by objection. I think all Reid is saying is that he has 50 votes to proceed to the bill. That doesn't get him the 60 he needs to pass something, or prevent 40 from blocking, however you want to look at it.
You can bet that the simple majority vote to take up a gun control bill will be splashed in the media as a major Obama/Democrat success. Don't fall for it.
