After repeatedly refusing to change positions on issues dear to conservative Republicans, Rudy Giuliani may have made a monumental gaffe this week, when he — the former mayor of New York — told reporters he is rooting for the Boston Red Sox in this World Series.

Remember, this is a guy who slammed Hillary Rodham Clinton when she, a Chicago Cubs fan, announced she was also a Yankees fan — an announcement timed to her run for New York's Senate seat.

But if his conversion alone wasn't enough, now the New York Daily News has the evidence it's also a giant flip-flop. Just months ago, he told the Providence Journal he would never embrace the Sox, even if it meant winning the presidency.

"I'm a Yankee fan," Giuliani said then. "I always believe it's a sign of my being straight with people, about not wanting to fool them, that I was one of the first mayors to be willing to say I was a Yankee fan."

So does it matter? Probably not.

But given that Giuliani made pretty much the same pitch to religious conservatives this weekend — "we have many, many more areas of agreement and the one thing you can count on with me is I'll always be honest with you" — you can bet some of them are wondering what other principles are on the table.
