A man who support partial-birth abortion WILL NOT appoint a justice like John Roberts!
Giuliani was the number three Justice Dept official in the Reagan administration. He was a US Attorney in the Reagan Administration.
I believe that he will appoint the type of lawyers who were his colleagues and previous hires, which would be of the Roberts and Alito mold.
He won't ask their opinion on abortion but would trust their decisions.
How they would vote on abortion will not be certain. It never is. (If either Roberts or Alito show any inclination not to overturn Roe, it's a dead issue anyway.)
Reagan appointed Kennedy. Bush appointed Souter.
Giuliani would do no worse. I believe better.
And there is more to the Presidency then the roulette wheel that is the Supreme Court. Of which there is never a guarantee.
