Fight?
As in pro-wrestling?
Like where they talk a whole bunch of smack in front of the camera, then get in the ring and do a nice little show with all sorts of amazing acrobatics and flips and sling shotting off the ropes at each other, then afterwards they all go to the same bar and get drunk and go back to their hotel room and pass around the groupies?
That type of fight?
Yup. Look at Ted Cruz. Railed against the bill, admonished its secrecy and offered an amendment to stop the import of illegal aliens (after voting to move the bill forward).
Cruz then votes to end debate. His amendment goes down in flames. The bill remains secret.
So what does Cruz do on the final vote?
He votes FOR it!!
