Not a lot of 'A' Civics students here.  It would have made absolutely no difference in this decision had Obama, Hillary, Sara or myself been elected the last time around.  This is a result of past appointments to the Court, which are for life.  Obama has only put one person on the Court, replacing someone who would have voted the same way.  5-4 decisions have been par for the course for the last 15 or so years, and until one of those 5 (Roberts, Alito, Scalia, Thomas and Kennedy) retires and is replaced with someone less conservative and less activist it's going to remain the standard decision.
