Speaking before the World Affairs Council and the City Club of Seattle, he said that British Prime Minister Tony Blair "has literally sacrificed his political career because of Iraq . . . that is a great testament to his political courage."
When asked by a reporter if he was in danger of making the same sacrifice, McCain responded, "Sure."
Senator McCain lost the Republican nomination to President Bush in 2000. He is expected to officially announce his second campaign for the White House next month.
