Yes, but the the GOPe can say they tried. That's all that matters, "A" for effort.
What they’re saying they’ll do is nothing more than their famous “show votes” they all collude to be able to go home and say “I voted no”. What they really do is vote to bring a controversial bill to the floor for a vote when they KNOW they have a chance to kill it outright if they stick together and don’t vote for cloture. Backstabbing traitors.
