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

4) Vote for cloture on the original bill and then vote against it.

Option (4) would have been the grown up and responsible thing to do--the bill had, probably, majority support and the consequences of not bailing out the auto industry are dire. Allowing a vote is not synonymous with acquiescing or voting in favor of the bill.
