My personal favorite for Pres candidate is Jeb Bush with Condi as VP. I think that is a ticket that would have an excellent chance of beating Hillary.
Jeb Bush can point at his very successful tenure as Governor. Most presidents were governors before they became president, it demonstrates ability to manage a state.
After the way the Terri Schiavo situation unfolded, I am fairly certain that Jeb Bush is through politically. I may be wrong, but I doubt it.
