I recently saw an editorial in THE WALL STREET JOURNAL that asked if John McCain is too old to be president. This editorial listed the world leaders who assumed leadership of their countries when they were 60+.
Remember Winston Churchill? He was 65 when he was prime minister during the war, and when he took office again in 1951 he was 76. Konrad Adenauer became the first chancellor of West Germany when he was 73. He led his country back from the destruction of WWII. Golda Meir was 70 when she became prime minister of Israel. She addressed Palestinian terrorism and presided over Israel's victory in the Yom Kippur War. After being imprisoned for 27 years, Nelson Mandela became the first democfatically elected president of South Africa. He was 75 and his was a presidency where his nation went from apartheid to integrated democratic rule.
There was a time when I thought John McCain was too old to be president. I changed my mind when I saw that he brought his mother to one of his campaign stops. She's 96.
