Rudy Giuliani said in an interview today that if Sarah Palin decides to become a presidential candidate, she should not "fall into the trap that I fell into" during the 2008 campaign, ......

The Republican former New York City mayor agreed that, like him, but "for different reasons," Palin has high national name recognition.

Giuliani said that while he won't decide until later summer whether to run for President because he wants to see "how the field develops," if he does, "I'd never run the campaign like the one I ran three years ago. That was a big mistake."
