Actually, if you read closely, the Kochs have signaled to all Republicans that they may vote "no" by citing the excessive "generousness" of this bill. (See e.g., Rand Paul)

Folks like Corrupt Cory prosper by moving in the quiet, dark corners of policy, not the bright sunlight. The question is: does he wish to continue in elective politics in Colorado or is he ready to collect his reward of Koch subsidy in the private sector? 

Colorado is one of the "bluest" states represented by a Republican in the Senate. All the propaganda in the world isn't going to make voters in Colorado forget who wrote this bill. Garnder cannot survive a "yes" vote.
