I hope they will do it. To be truly honest I want to see congressional action on the bill, even if it fails.

I wonder could they just write the defence authorization to contain DA in it to begin with (lemme change that, will they cause I know you CAN put anything you want in the bill as long as its fine according to US constitution), rather than add it during debate. That way DA won't need 60 votes, the whole package will need 51 (under Byrd's rule*) votes to pass and have debate time cut to 50 hours.
