Arizona Sen. John McCain says Republican rival Rudy Giuliani is deservedly popular because of his efforts on 9/11, but that it will take more than that to defeat Democrat Hillary Rodham Clinton and win the presidency. McCain attributed Giuliani's standing atop the GOP field to the fact that he is so recognized from Sept. 11, 2001. "I think because he is deservedly a popular individual who was - his performance after 9/11 was very excellent, and he rallied the country," McCain said, adding that he had praised McCain's performance and even accompanied him to the World Series when the Arizona Diamondbacks defeated the Yankees.

But McCain, without naming Giuliani, expressed doubt that a candidate with his views would become the GOP nominee. McCain contended the former New York mayor is out of step with the party's conservative wing because he supports abortion and gay rights and gun control.

"I'm hoping that whoever is the nominee of our party, that we will support that nominee," McCain said on ABC's "This Week.""But it's hard for me to imagine that someone who holds the views on some of these issues and a record of it, would be at the end of the day the nominee of the party."

McCain emphasized his "consistent, conservative, reliable record" and said he is the most likely to be able to defeat Sen. Hillary Rodham Clinton, D-N.Y., in a general election.

About his own campaign, which at one point had appeared doomed, McCain dismissed talk that he doesn't have enough money to stay competitive.

"I have never won a campaign on money," he said, pointing to his defeat of President Bush in the New Hampshire primary in 2000 despite being outspent.

McCain praised that state and Iowa for being places where voters insist on getting up close and personal with the candidates.

"It's good for America, but it's also very good for my campaign. And I see increased enthusiasm," he said. "I see increasing support, and I think we're going to do very well. And whatever we do, I think we'll have enough money to be competitive."
