I think it is really important to point out that the Republicans had many alternatives to avail themselves and that they chose the worst possible one.
1) Cooperate with White House and Democratic negotiators earlier in the process
2) Negotiate in good faith with Reid following the failure of the original bill
3) Pass the original bill
