The Republicans aren't just the Party of No, they're the Party of Start Over.
Of course, "start over" is just another form of "no." There's no actual intention to start over. Again, it's a classic scorpion move: Give me a ride across the river. I promise I won't sting you. In this case: Let's start over. I promise we won't obstruct whatever the new "restarted" bill might be. But, naturally, they will.
