George Will makes the case:
Giuliani has a way to go before he can seal the deal, but he’s saying the right things. Conservatives can trust him to nominate judges who will follow the Constitution rather than reshape social policy from the bench. That’s what conservatives want to hear, and if Giuliani strongly makes that point, it will help him. There are still going to be questions about Giuliani’s position on abortion and gun control, but I don’t see those as being fatal to his campaign — unless he bombs them.
Giuliani’s biggest asset is his leadership — he did great things for the City of New York, and he’s a tenacious when it comes to getting things done. This country needs someone like that. Even if Giuliani alienates some on the social right, he can also bring in many moderates, and it’s the moderates abandoning the GOP in 2006 that cost the Republicans control of Congress.
