Today, March 16, 2018, former President Jimmy Carter has surpassed Gerald Ford in age longevity, and earlier had done so past Ronald Reagan on January 30.
Only George H. W. Bush, 111 days older than Carter, is still ahead of Carter.
So we have right now four straight Presidents who have reached 93–Ronald Reagan, Gerald Ford, George H. W. Bush. Jimmy Carter.
On June 12, Bush will be 94, and Carter will reach that age on October 1.
Right now, it would seem that Carter will outlive Bush, but considering that Carter had a cancer diagnosis two and a half years ago, who can say who will have the age record ultimately?
The age longevity issue is amazing, as when one looks at the Presidential Election of 1976, all four candidates on the ballot–Carter, Ford, Walter Mondale, and Bob Dole–all reached the age of 90 and Mondale is now that age, and Dole is 94, and just was awarded a Congressional Gold Medal recently,
And in 1980, when we had a third independent candidacy, all six candidates on the ballot–Carter, Reagan, Bush, Mondale, and also John Anderson and Patrick Lucey—all reached the 90s, and Anderson died last December at 95, and Lucey, his Vice Presidential running mate, died at 96 in 2014.
Further back, in 1972, the losing Democratic ticket of George McGovern died at age 90 in 2012, and Vice Presidential running mate Sargent Shriver died at age 95 in 2011.
This is all the story of the growing longevity of Americans, not just public figures.
