I wonder if the Dims realize that they can't get away with the same things in the past, since now there are alternative news outlets and the internet to challenge their coordinated attacks. Thus, they can't waste too much many watts here.
I think that they are holding out for the other nominee. But if the next one is as articulate and quick on their feet as John Roberts, they aren't going to convince John Q. Public that the second nominee isn't qualified either. Then again, John Q. Public doesn't get to vote on Supreme Court justices.
The Supreme Court is the big one - this will steer the country for the next 20 years. It is imperative that the leftist tilt be eliminated, but the leftists see it a bit differently - they want to hold that last gasp of power that they still retain in the judicial branch. It is the only way that their socialism can be expanded. The people would never stand for it at the legislative end.
