My AP U.S. History teacher at school, Betsy Newmark, had this to say about the places Roberts will go with his position on the courts. Very interesting...
It seems that, once Roberts is confirmed, that he will become the clear choice for Chief Justice if Rehnquist steps down. Roberts clerked for Rehnquist and apparently the Chief thinks very highly of him. I predict that, after a year or two, Rehnquist will step down while Bush is still president and give Bush the opportunity to elevate Roberts to be Chief.

Two years ago, Supreme Court Justice Scalia had this to say about Roberts, whom he called "far and away the best Supreme Court litigator in the country":
No matter how intense the questioning, Roberts is never flustered, and is always able to calmly answer any question whatsoever, while skillfully weaving in the substantive points that he wanted to make in the first place.

Now it's a waiting game...what will happen? It'll be an interesting few days (if it even lasts that long).
