I believe leading up to the SCOTUS ruling on the ACA, the GOP began to feel very confident they were going to win -- and they began to realize that was the worst thing that could happen. How could they celebrate Americans losing their health care? That would look horrible politically. And what did they have to replace it with? Boehner sent out a memo asking people not to do a "victory lap." Many Republicans began mumbling about certain provisions that maybe weren't so bad, such as letting young people stay on their parent's plan. And if the SCOTUS killed the ACA, that would take away their best campaign issue, right? Last night many Republicans probably went to bed quietly hoping they'd lose. But now that they've lost, and they're hooking the jumper cables up to their Frankenstein's monster of a health care battle, they're probably back to wishing they had won.
Now the frame has been set: The GOP is fighting the battles of yesterday, and Obama is moving the country forward. This is a terrible position for them to be in.
