By the end of September 2007, most polls showed Giuliani to have more support than any of the other declared Republican candidates, with only Senator Thompson and Governor Romney showing greater support in some state polls. Specifically, state-by-state polls for the 2008 Republican nomination showed that Giuliani polled ahead of all other candidates in a majority of states including the delegate-rich states of California, New York, and Florida. A September 26, 2007 Quinnipiac poll taken in New Jersey gave the mayor a slight lead over Hillary Clinton in the traditional blue state, 45% to 44%.
