Quote from seasideheights:
The idea of the commission is to create 1 package that wouldn't be modified in the house or senate. It would be a simple up or down vote on the entire package.
Would that mean a simple majority to pass? ie: 51 Senate votes for passage, or could legislation formed by the commission still be filibustered by Republicans, which would then require 60 votes? If filibusters aren't allowed then I'd start worrying, especially if Obama is allowed to pick which Republicans would be on this commission.
