Giuliani cannot possibly win the primary without 'religious' conservatives. And it's going to be nearly impossible for him to get to the religious right of Romney, Brownback, Frist, or even McCain.
The same is basically true of Newt.
Now if enough of the red meat guys stay in the race to split the nutcase vote then Giuliani, McCain, and Newt have a fighting chance.
Giuliani is likely his own worse enemy . . . that and the Bush legacy. After the debacle of the unitary executive, the last thing the country wants is someone with an IQ>95 that believes in the theory of the unitary executive. His record in NYC is clearly double-edged. Plus after becoming 'America's Mayor' what did he do? Mad dash for dollars . . . including his great success at reducing crime in Mexico City :roll:
