DUBAI, United Arab Emirates — Rudy Giuliani said Sunday he will consider running for governor of New York and isn’t ruling out a second attempt at the U.S. presidency.

A one-time presidential front-runner and former mayor of New York City, Giuliani dropped out of the race for Republican nominee in January after losing the primary in Florida, where he had poured the bulk of his campaign resources.

“No one knows whether you’ll do something again until you come to the point of: ’Is it possible to do it again? Would you have a chance of winning?”’ he said of a second White House bid following a speech in Dubai. “I mean those are just things you can’t evaluate right now.”

He said Sunday he is not sure whether a different strategy would have won him the nomination. The financial crisis gave Democrats a natural advantage in this month’s elections, he said.
