He's done. According to the NYT, Giuliani plans on being much more forthright about his support of abortion rights and press his campaign in states where he thinks it will be more well-received. In a way, it's a relief. His half-way talk of "I hate abortion" (which I always took to mean "I hate that abortion matters in Republican politics because it means I'll never get to be President unless we can find some way around it"...) wasn't ever going to get the job done for him. But here's the clear truth of the matter: Giuliani wants to be President and is firmly in favor of a constitutionalized right to kill unborn children *and* thinks that the Congress should spend tax dollars to assist those procedures. He's a consistent supporter of Planned Parenthood and NARAL Pro-Death America.
Make him CIA director and sic him on the bad guys. But not President, no way.
