How long will they last? Both Kagan is obese and Sotomayor is heavy and has type I Diabetes since age 8. Kagan is a little younger than Sotomayor but she's HUGE and her health issues will start to appear. She has to have high blood pressure and Type II Diabetes can't be too far off.
Good points. You left off the fact that Ginsberg has had pancriatic cancer for a few years, but Obama will probably get a chance to replace her. No matter who he nominates he will have a hard time getting confirmation just like he did recently with Lui for the 9th circus court.
