For all of the people claiming the presidential candidate matters due to judicial appointments, I bring you the Supreme Court, their stance on the Heller decision, and their appointing president:

Justice	Heller Stance	Appointed by
Ruth Bader Ginsburg	Dissent	Bill Clinton
Stephen Breyer	Dissent	Bill Clinton
David Souter	Dissent	George Bush, Sr.
John Paul Stevens	Dissent	Gerald Ford
Anthony Kennedy	Affirmed	Ronald Reagan
Clarence Thomas	Affirmed	George Bush, Sr.
John Roberts	Affirmed	George Bush, Jr.
Samuel Alito	Affirmed	George Bush, Jr.
Antonin Scalia	Affirmed	Ronald Reagan

Half of the dissenters were appointed by Republicans. This was a 5-4 vote with 7 Republican appointees on the court. How can we count on McCain to appoint a conservative justice?
