Broder's idea does seem reasonable at first glance. It's only when a person realizes that Democrats have never kept up their end of the deal in any bargain that one sees that it's worthless.
That being said, I wouldn't be at all surprised to find that the Republican leadership would go along with it because it would give them political "cover". They could keep claiming that they're "on our side and did their best" but that the Dems lied and so things continue to slide downhill. We've given Republicans all the power they'd ever need to do what's right and, as fas as I'm concerned, they either do it now or they're finished.
they can't stop a philabuster right now. They dont have that much power.
they might after the 2006 election cycle, but as of right now, they are just short of where they need to be.
