A resurgent John McCain will return to Los Angeles on Jan. 31 to raise money at the home of MGM chief Harry Sloan.

Sloan hosted a fund-raiser for McCain a year ago, when it was assumed that the Arizona senator would be the de facto front runner. But his campaign stumbled and struggled to raise money, and in entertainment, Rudy Giuliani started to draw some of the boldfaced names. Among those who are backing the New York mayor are Kelsey Grammer, Robert Duvall, Adam Sandler and Dennis Miller. Jon Voight endorsed Giuliani on Monday.

As of now, there haven’t been any major defections from the Giuliani camp, even as pundits and analysts question the wisdom of his strategy of focusing on Florida and the Feb. 5 primary states.

“There has been no leakage on this side,” says a Giuliani donor in the entertainment industry.

But even Giuliani supporters admit that he has to win Florida or at least meet expectations there. A Quinnipiac University poll shows him falling slightly behind McCain in the Sunshine State. And McCain also holds a slight lead in California in the most recent Politico/CNN/Los Angeles Times poll.
