John McCain started his day outside the Rockefeller Center in New York. He told supporters that he was the man to keep Americans safe and added that he would find Osama bin Laden.
"I'll look you in the eye and tell you that if I have to follow him to the gates of hell I will get Osama bin Laden. I will bring him to justice," said McCain.
The former POW stressed to the crowd his national security credentials with Rudy Giuliani by his side.
"I believe without any doubt that the best choice that Republicans have for president of the United States is Senator John McCain," said Giuliani.
New York is a key state and more than 100 Republican delegates are at stake in the winner takes all primary. California is the biggest prize with 170 delegates. McCain has been projected the winner of California's Republican primary over his chief rival Mitt Romney. McCain made one last campaign stop in California Tuesday at Jim's Air Aviation in San Diego.
Appearing at the San Diego airport hangar with California Gov.Arnold Schwarzenegger before flying to his home state of Arizona, the Republican front-runner noted that both of them had reputations for cooperating with the opposition party when necessary.
"I am running for president because of the transcendent challenge of the 21st century which is radical Islamic extremism as you know," said McCain.
He introduced the crowd of about 150 to his mother, Roberta, who turns 96 on Thursday, "if anyone has any concerns about my age," said McCain. The Arizona senator is 71.
"The economy is a key issue, getting out of this war would be a real plus. Someone who has a vision for the country and is not glued to the past," said John Town, a Phoenix resident.
As to a possible fall matchup with either Hillary Rodham Clinton or Barack Obama, McCain said that he had seen the national polls and that they suggested "I defeat Clinton and Obama in a general election matchup."
