Nixon identified himself as a crisis-laden man. He'd reach levels of victory and then he'd plunge into defeat. He was vice president, then he lost to Kennedy, then he lost the California governorship. Then came a great comeback and then he blew it again - and the next comeback, after he lost the presidency.
