But as Laurence Tribe mentioned in his talk you'll see cases where Supreme Court rules 5-4 in favor of the Left, but where the so-called swing vote Anthony Kennedy who I believe is more of a Libertarian than anything else, at least a Conservative Libertarian will rule with the Right. And with Chief Justice Roberts or Justice Sam Alito ruling with the Left instead of Justice Kennedy. Or Justice Antonin Scalia perhaps the Tea Party's favorite Justice ruling with the Left when it comes with the privacy issues.
Actually if you look at most of the Supreme Court decisions they tend not to be 5-4 either way. And a lot of them are 6-3 or 7-2. The Justices agree on a lot more than they get credit for. Its really just the controversial decisions where there are clear differences between the Left and Right that makes the Supreme Court look a lot more partisan than it is. Like with campaign finance or corporate power, unions affirmative action to use as examples. So the Supreme Court is not as radical as it tends to get portrayed especially by the radical-left.
