Saying Mitt Romney has “the resume and background for the job,” former New York City Mayor Rudolph Giuliani endorsed the likely Republican nominee for president today. “I think he has an understanding of the economy that’s far deeper than the president and far deeper than most people,” Giuliani said, “and I think he has the strength and toughness to handle foreign policy.” Giuliani had, until today, been highly critical of Romney, even after the two were no longer political rivals.
