Only Cruz? Lots of names on that list. It was a cloture vote, not a vote for TPP.
Sadly the cloture vote is the only vote that really matters. These scum have fooled the voter for years by voting cloture then ducking the vote on the floor to say they voted agains it, or vice versa.
Remember back in the day when the Republicans drove Tip O'Neal crazy with special orders? They would always ask unanimous consent "To revise and extend my remarks, even to include extraneous materials." Meaning they could say the sky is blue then deny there is even a sky in their revision.
