I'm not going to go so far as to accuse liberals of being happy that Antonin Scalia died (even though I saw a few on Facebook who unapologetically were). I don't think it would be accurate to generalize that there was a yay death spirit permeating the entire left. But what I will say is this: Power politics is all the time for the left, and they really don't care what kind of advantage they're handed. They'll take advantage of it. And nowhere is power politics more essential to the left than in the realm of the public employee unions - which could not exist at all if not for laws mandating that they must - and that public employees must pay dues to them whether they want to or not.
At oral arguments in December, it looked as if Friedrichs vs. California Teachers Assn. was going to go the way of plaintiff Rebecca Friedrichs, a veteran teacher who was tired of paying dues to an organization she didn't even want to be a member of. Although a lower court had found in favor of the union, a 5-man majority of the Justices seemed to be leaning toward the view that public employees have the right to make the decision.
