The Supreme Court seems more and more to be a very conservative, almost reactionary, Court in so many ways, but David Broder of the Washington Post believes that having three women on the Court at the same time (Ruth Bader Ginsberg, Sonia Sotomayor, Elena Kagan) has to affect the Supreme Court in ways hard to fathom now!
The author hopes the role of women will have a positive effect, but the problem is that it is likely that Ruth Bader Ginsberg will leave the Court before the Presidential election, and that it will be impossible for Obama to select a replacement as liberal as Ginsberg has been!
This is particularly true with a Senate bound to be of a smaller Democratic majority, and even the slight possibility of a GOP majority! 
So it seems likely that in comparison to now, the Supreme Court might actually be MORE conservative, as a result, than it is right now!
