from Fox News article:
Among conservatives, Giuliani’s support falls from 57
percent in the head-to-head race against Clinton
to 42 percent when a third-party conservative is included.
"While some of the conservative Christian leaders are
sounding more positive about Mitt Romney despite his Mormonism, by and large
they are still very negative about Giuliani," said John Gorman, chairman
of Opinion Dynamics. "A significant fraction of voters who might otherwise
support the Republican are also clearly not fans of the former mayor. If given
a chance, they say they’ll vote for someone else. This might diminish somewhat
if the election of Clinton
becomes more threatening to them, but given the narrowness of recent elections,
even a few points could be decisive."
