A new Quinnipiac poll shows Republican presidential candidate Rick Santorum with a substantial lead over Mitt Romney in Santorum's home state of Pennsylvania as Romney picks up a new endorsement.
According to the poll, 36 percent of Pennsylvania Republicans favor Santorum, compared to Romney's 22 percent. Another 12 percent back Ron Paul, while 8 percent support Newt Gingrich.
Former Homeland Security Secretary and former Pennsylvania Governor Tom Ridge, who previously endorsed Jon Huntsman before the former ambassador left the race, endorsed Romney Wednesday.
"Having spent most my life in public service, as a soldier, as a congressman, as a governor of Pennsylvania, as a White House official and as a Secretary of Homeland Security, I've met accomplished and strong leaders in my life," Ridge said in his endorsement. "Mitt Romney is one of them. He would bring to the presidency an extraordinary set of skills."
Ridge praised Romney's work in the private sector in his endorsement, and also said the 2002 Olympics demonstrated Romney's "genuine ability to command in facing the security problems that cropped up for the Games in the aftermath of the 9/11 attacks."
