A Gentle Reminder of the Stakes
With this in mind--Current Supreme Court Justice Age---

John Paul Stevens (88)
Ruth Bader Ginsburg (75)
Antonin Scalia (72)
Anthony Kennedy (72)
Steven Breyer (70)
David Souter (68)
Clarence Thomas (60)
Samuel Alito (58)
John Roberts (53)

Consider the Republican candidates' answer to this question: Do you think Roe v. Wade should be overturned?

From John McCain's campaign website:

John McCain believes Roe v. Wade is a flawed decision that must be overturned, and as president he will nominate judges who understand...

From Sarah Palin's interview with Charles Gibson:

GIBSON: Roe v. Wade, do you think it should be reversed?

PALIN: I think it should and I think that states should be able to decide that issue... I am pro-life.

4 Justices - Alito, Scalia, Roberts and Thomas - sit poised to overturn a woman's right to make her own reproductive decisions. The 5 who would not are among the 6 oldest members of the court. Roe would simply not survive a McCain-Palin administration in its current state.
