Former New York City Mayor Rudy Giuliani said he's more likely to run for president if former Alaska Gov. Sarah Palin runs.
In an interview on CNN's "Piers Morgan Tonight," Giuliani, who dropped out of the 2008 Republican presidential primary, said running against Palin for the 2012 GOP nomination would show him as a moderate Republican.
"The more Republicans in which I can show a contrast, probably the better chance, the better chance that I have," Giuliani told CNN's Piers Morgan in an interview set to air at 9 pm. ET Monday. Portions of the interview will air Friday (tonight) on CNN's "John King, USA" at 7 p.m. ET.
