Rush explained the old DC Insider ploy years ago. When so called conservatives actually have the power to stop bad legislation, they vote with the Dems. Then, after the legislation is a done deal, so called conservatives make a big hoopla about voting against it—i.e.: when voting against it has become a meaningless exercise.
The only way TPP could have been stopped would have been to deny Obama fast track. Cruz gave Obama that destructively vast power...and then made a big hoopla about the meaningless votes that followed.
