McCain's second time on the New Hampshire ballot
CONCORD, New Hampshire (CNN) - Walking up the steps of the statehouse Tuesday, Sen. John McCain, R-Arizona, filed as a candidate in the New Hampshire presidential primary for the second time.
"Great to see you again, you haven't aged a bit since we did this in 2000," McCain said as he drew laughs from New Hampshire Secretary of State William Gardner.
When later asked by a reporter about his age, McCain compared his qualifications against those of his competitors, former New York Mayor Rudy Giuliani and former Massachusetts Gov. Mitt Romney.
"I think it's great to have been a mayor of a big city, I think it's great to have been governor of a state. I think it’s important that I have been involved in every national security issue since 1980," he said.
Giuliani who arrived three and a half hours later to file his own paperwork responded to McCain's words with praise.
"John has lots of credentials. He’s a close friend of mine and he's someone I admire very very much. John has every right to argue his credentials and put them in front of the American people."
He then added, "A long time ago I was once asked to do a negative ad against John McCain and I said no how, no way."
