There is a huge misperception out there about the Supreme Court. Most people think that the majority of cases that go to the Supreme Court end up being decided by a bare 5-4 majority along party lines. That is completely false. That rarely happens. Over the past few years, around 70% of the cases were decided by a unanimous vote. It is rare that the vote is 5-4, and when it is, it is rarely on party lines. There were only 4 cases out of the last 72 cases that were decided by a 5-4 vote that went along party lines.
