Ironically, Giuliani might be the most reliable candidate when it comes to many conservative issues (such as tax cuts) because he has the most to prove to conservative Republicans. He promises to appoint Scalia/Thomas/Alito-type judges.
I honestly think I could hold my nose and vote for Giuliani easier than I could for Mitt or the Huckster.
Giuliani has told Larry King (and others) that his idea of a “strict constructionist” might support Roe v. Wade.
