Giuliani is a tricky issue for me. So many pros, so many cons. If he's solid on judge-picking, and vows to keep out of (further liberalizing of) abortion and most if not all gun control, then I may be able to support him. The two biggest issues for me are judge-picking at defense/WOT, although there are of course many more issues.
Please review Giuliani's record for picking judges or picking the committee that picks the judges for him. You'll have your answer about whether to support Giuliani or not.
