Governing, however, is a different story. The framers wanted a strong executive but one who was accountable, too, reined in by shared and separated powers. As a consequence, the president can’t simply impose — he needs consensus and cooperation. William Howard Taft lamented a century ago that the president “cannot make the corn to grow, he cannot make business good.” President Obama knows this constraint well: A president can’t create jobs, will victory in the two longest wars in American history, protect the nation from the European debt crisis or even plug an oil leak in the Gulf of Mexico.
2. War enhances a president’s power and reputation.
This was true for Abraham Lincoln and Franklin D. Roosevelt, whose reputations were strengthened by wars won decisively as a result of their efforts in office. When I asked Jimmy Carter why we haven’t had a great president since FDR, he replied, “Because we haven’t had a good war.”
But for most 20th-century presidents, military conflict has hurt rather than helped them. Harry Truman left office with an approval rating of 32 percent, largely because of the stalemated war in Korea; Lyndon Johnson chose not to run again in 1968 because of the Vietnam quagmire. George H.W. Bush won his war against Saddam Hussein, but he conflated that victory with what Americans really cared about, a sagging economy, and this contributed to his failure to win reelection. George W. Bush is hoping for the best in his Iraq war, but history is likely to deliver some unkind cuts. Obama doubled down in Afghanistan and now owns that war, but is seeking an early exit. Of late, getting out of wars has been better for a president than getting into them.
3. You must have a strong character to be a successful president.
Character is critical to a president’s legacy: Think of George Washington’s probity and realism; Lincoln’s willfulness and compassion; FDR’s confidence and optimism.
But character is tough to assess. Is it defined by personal behavior? Or does it pertain only to civic and public performance? FDR was an adulterer but a great president. John F. Kennedy was a womanizer (as former White House intern Mimi Alford’s recent book reminds us yet again), but he gets high marks for inspiring a nation and averting nuclear war.
LBJ deceived the public about Vietnam, yet his civil rights legislation and parts of his Great Society programs made him a transformative president. And what about Richard Nixon, who undermined the constitutional system he was sworn to protect but was one of the most consequential foreign policy presidents?
Americans want and deserve presidents who play by the rules in public and private, but we seem confused about what’s acceptable. Bill Clinton’s sexual escapades with Monica Lewinsky undermined the integrity of the presidency — yet he left office with one of the highest approval ratings of any president.
4. The best presidents are highly educated and have long experience in government.
There’s no ideal preparation for the presidency. Experience in state and public affairs can be critical — of our 43 presidents, 34 had backgrounds in law, government or the military. But James Buchanan and Herbert Hoover had two of the best résumés in the business and yet were ill-equipped to handle the crises they confronted — the drift toward civil war and economic calamity, respectively.
Carter was a nuclear engineer, Annapolis grad and submariner, yet he was not nearly as consequential a president as Truman, our only 20th-century president without a college degree. Washington and Lincoln had little formal education. FDR finished Harvard in three years and dropped out of law school, but he had deep experience in government as assistant secretary of the Navy and governor of New York.
We’ve had only one PhD president: Woodrow Wilson. Professors in chief are rare, largely because life experience, usually with hard knocks along the way — not a fancy degree — is the critical preparation for being president. Emotional IQ can be more valuable than intellect: Can you keep internal demons under control, exercise good judgment, and read people and situations accurately? JFK was lucky to be sure in his showdown with Russia over nuclear missiles in Cuba, but he was also grounded enough to balance strength and prudence to get out of the nuclear standoff with Nikita Khrushchev.
5. The stresses of the presidency are hazardous to your health and shorten your life span.
Unless you fall to the assassin’s bullet (as Lincoln, James Garfield, William McKinley and Kennedy did), the presidency isn’t a killer job. Our first eight presidents lived an average of 79.8 years when life expectancy for American men was around 40 years.
S. Jay Olshansky, an expert on aging, found that many presidents have lived much longer than expected, particularly in the modern era. He subtracted two days of life for every day in office to compensate for claims that presidents age twice as fast, and then he compared the estimated life span at age of inauguration with the actual life span of each president who died of natural causes. From Hoover through Ronald Reagan (excluding Kennedy), seven of eight lived longer than expected. Johnson was an exception; he died of a heart attack at 64. But the average age at death was 81.6 years. And four of our 43 presidents lived to their 90s: Gerald Ford, Reagan, John Adams and Hoover.
The presidency will give you more wrinkles and gray hair, but it’s not likely to kill you.
