So why doesn't any Republican stand up and say, "Since the Democrats have the sixty votes to move this bill forward I am willing to vote for this bill for free and you can rescind the goodies offered to Sen. Nelson."?
The reason that no Republicans will stand in for any democrat vote is that they want the goodies too. If they kill horse trading how will they be able to trade their votes when they have power?
So they scream while they bide their time until they can get their hands in the cookie jar.
