In their second term in office, the thoughts of any US president turn to their legacy.George W Bush has some of the lowest opinion poll ratings of any modern president and his critics say his legacy will be the continuing war in Iraq and a weakening economy.
But for the people who formed the core of his support in the 2000 and 2004 elections, there is something else that is just as important and possibly even more important.
President Bush has made two appointments to the nine-member Supreme Court and voters from the Christian Conservative movement say that is his true legacy.
Conservatives strengthened
For more than a decade the court was finely balanced. On one side were conservative justices who believe in a very literal application of the Constitution.
On the other, there were the more liberal judges who see the Constitution as more of a living document open to greater interpretation.
Mr Bush's appoints of John Roberts and Samuel Alito to the bench has entrenched the conservative side. And the impact has already been seen in rulings on sensitive issues like abortion rights.
