In the latest poll, the former New York mayor led among
Republicans with 44 percent to McCain's 21 percent. Last month,
Giuliani led with 34 percent to McCain's 27 percent.
Former House speaker Newt Gingrich of Georgia ran third in the
latest poll with 15 percent, while former Massachusetts governor
Mitt Romney was fourth with 4 percent. Gingrich has not said he
definitely plans to run, and without him, Giuliani's lead would
increase even more, to 53 percent compared with McCain's 23
percent.
