That IS the problem with conservative judges. They do not legislate from the bench. They look at the facts and the merits of the case and then make their decision. Those who think that a conservative court is going to turn back years of liberal excess are delusional. Liberals use the court as a battering ram, conservatives use it as a mediating tool, big difference. The best we can hope for from a conservative court is that they don't make matters worse, not that they will clean up the mess that is already here.
When a previous decision is clearly in violation of the Constitution, the Supreme Court has an obligation to take the case and overturn the unconstitutional ruling.
Overturning liberal judicial activism is not legislating from the bench. It's protecting the Constitution.
