Giuliani should have run against her for the Senate because he CANNOT win in a national election. New York State is so liberal that his position on abortion does not matter there. It does out here in the "other" America.
If any pro-abort candidate wins the Republican nomination, which I think unlikely, he will still not win the general election. I can get on board behind a candidate who doesn't agree with me on many issues, but not that one, and there are many others who feel the same way. We'll vote third-party or stay home (I'd take the first option myself).
