So now that Obama's been sworn in, and since we've already seen him act in a lot of areas already, I think it's time to start predicting the one thing Obama can't do on a set timetable: appoint new justices. First off, a list of the current justices in order of seniority: Chief Justice John Roberts; Age: 53; Appointed by: Bush Jr. [*]John Paul Stevens; Age: 88; Appointed by: Ford [*]Antonin Scalia; Age: 72; Appointed by: Reagan Anthony Kennedy; Age: 72; Appointed by: Reagan [*]David Souter; Age: 69; Appointed by: Bush Sr. [*]Clarence Thomas; Age: 60; Appointed by: Bush Sr. [*]Ruth Bader Ginsburg; Age: 75; Appointed by: Clinton [*]Stephen Breyer; Age: 70; Appointed by: Clinton [*]Samuel Alito; Age: 58; Appointed by: Bush Jr. Justices highlighted in red are on the conservative end of the spectrum while those in blue are on the liberal end of the spectrum, with Justice Kennedy as the middle justice. So, here's the game: predict who will leave the Court first, when, and if you're really daring, who Obama will pick to replace him/her. Prize: Bragging rights.
