Former New York City mayor Rudy Giuliani, who lost the 2008 Republican presidential nomination to John McCain, criticized his own party for its social conservatism during a CNN interview yesterday. While expressing personal fondness for Rick Santorum, he stressed their "big differences on social issues" (presumably, for example, the question of whether Satan is devouring Americans' souls) and warned that opposition to gay rights "makes the party look like it isn't a modern party — it doesn’t understand the modern world."
Giuliani supports civil unions for same-sex couples, not gay marriage, but the latter doesn't bother him. In the same interview, he worried that inflexibility on social issues would make it difficult for the Republican Party to "get back the Northeast as a voting bloc," and speculated that it "absolutely" could lead to a third-party split.
He also reiterated his pro-choice stance on abortion, which is "why I couldn't get nominated," despite his reliably conservative stances on many other issues such as 9/11 and 9/11.
