I can not remember a time in the past where 80% of the American people were opposed to something that 60% of Congress supported. I don't think that the bill survives the House, even if it makes it through the Senate (on a fast-gaveled procedural vote taken at 6:00pm on a Friday evening before a holiday recess - just watch). If it does, and the President signs it, all Hell is going to break loose in this country.
No matter how it happens if this POS bill passes Repubs are going to have such hell to pay they'd wish Bill Clinton was back in office before the wrath of this electorate comes down on them!
