Blame directed towards the Supreme Court is misplaced. While some decisions have always seemed partisan, the real fault lies with Congress. The higher courts only come into play when the law is ambiguous or contradictory because Congress did a bad job. At that point any legal decision becomes something of a toss up, and even if the Supreme Court issues the "right" decision today they might reverse themselves tomorrow. Unless voters hold Congress accountable then nothing will improve.

For example, maybe a future President will nominate Supreme Court justices who will overturn the notorious Citizens United v. FEC decision. But ultimately the only stable solution will be to follow the defined process and amend the Constitution rather than trying to patch around it. Yes, that will be difficult but nothing else can really work.
