The bill’s ultimate passage was assured on Wednesday when Democrats agreed to forgo a filibuster in return for consideration of the amendment. Any changes in the Senate bill, however, would have made it impossible for Republican leaders to meet their goal of sending the bill to the White House before adjourning on Friday to hit the campaign trail.So the Democrats cut a deal, exchanging their filibuster rights to get amendments heard which, if not passed, would make the bill that much more filibuster-worthy.
Fucking duh. They basically handed the GOP all the reason in the world not to pass the amendment. If they passed it, they would have had to delay sending it to the White House; if they didn’t, they met their goal—and in agreeing to “consider” the amendment, they guaranteed that the Dems wouldn’t filibuster.
