Yes, they do, and on all levels, not just the SC.
There are those that say Obama would have been a great SCJ and he doesn't disagree, and this is a man that called the Constitution a "a charter of negative liberties." Now would he really rule based on the Constitution? I'll answer, no.
The SCJs that he appointed reflect his views.
The main problem isn't the SC, it's a congress that refuses to allow the Constitution to guide them which brings cases to the SC that they should never have to rule on in the first place. (Obamacare being one example)
