Bush43`s two appointments to the SCOTUS are in the early stages of their tenure. What happens 10-20 years down the road is an unknown factor at this time. No one can see into the future. So far, so good.
Bush43 has always been an open borders/amnesty. He supports liberal immigration reform as spelled out in Senate bill S2611. Bush, Giuliani and McCain all want comprehensive immigration reform. They all opposed House bill HR 4437 when it passed the GOP House vote in Dec2005.
I don't understand why everybody thinks it's a wonderful idea if Giuliani commits to appointments like Bush's. Scalia and Thomas have not wavered and I can see wanting more like them, but until a lot more time has passed, we won't know much more than we knew about Bush's appointments prior to confirmation, although I remain hopeful.
