Since the presidential debate of June 27, national attention has been laser-focused on the question of Joe Biden’s competence to lead the country in a second term. Already the oldest President ever elected, if he comes out on top in November he will shatter his own record, re-taking office at age 81. On July 11 ABC News released polling data showing that 67% of Americans think he should drop out of the race because of his age, but 50% of voters believe that Trump also needs to step aside for a younger candidate.
What We Did and Why
As this political drama comes to a head, it’s worth looking at the historical context to understand how old our previous presidents were when they took office and what they achieved despite, or perhaps thanks to, their age and experience. We’ve consulted sources such as WhiteHouse.gov, the American Presidency Project, and Britannica to assemble comparative data on each President. They are arranged from youngest to oldest based on their age at inauguration.
Of course, nearly every President was controversial and some had scandals associated with them, but we’re focusing here on listing a few notable positive contributions of each. This illustrates that age is not necessarily a factor in a President being able to make positive contributions to the country. However, you will also note that the trend toward electing elderly people to the highest office in the land has become stronger in modern times. It’s worth considering why this is the case and what, if anything, should be done about it.
What Are the Qualifications to be President?
There is no maximum age limit for Presidential candidates, only minimum limits. According to the Constitution, a President must be at least 35 years old, must be a natural born citizen, and has to have lived in the United States for a minimum of 14 years. What is a natural born citizen? It is someone who was born a citizen and did not have to go through a legal process to become an American. So for example, if someone was born overseas, but to American parents, they could be eligible to run for President.
How Could an Age Limit Be Added to the Constitution?
Requiring an upward age limit for Presidential candidates would involve changing the Constitution—a process the Founders intentionally made quite difficult so that any changes would truly reflect a national consensus.
To propose an Amendment, either 2/3 of both houses of Congress (67 of 100 Senators and 290 out of 435 Representatives) have to approve it, or 2/3 of the states (34 states) can call for a constitutional convention. Once the Amendment passes one of those hurdles, it must be ratified by 3/4 of the country’s state legislatures (38 states). It’s such a strenuous process to reach this level of consensus that the Constitution has only been amended 27 times in the country’s 237-year history.
Are Presidential Age Limits Likely to Happen?
American culture has a noticeable bias toward youth and a tendency to think of age as a liability rather than an asset. There are arguments to be made on both sides, and we’ll give a few examples below. But the main reason a Presidential age limit is unlikely to be approved is that Senators, Representatives, and members of state legislatures often have their own Presidential ambitions. As many of them are also elderly, they would be the people most immediately disadvantaged by such a new condition.
As a general rule, it’s hard to get lawmakers to vote to restrict their own power. However, in a scenario where public backlash against aged candidates votes them out of office and creates a supermajority of younger legislators with a mandate for change, then Presidential and even Congressional age limits might be on the table.
Pros of an Age Limit
- Inspiration: A younger President can have a more youthful energy and ability to cast bold visions that capture the public imagination. They can also connect with younger generations and get them more involved politically.
- Energy: The Presidency is a demanding job. Everyone who has served in this role leaves office having visibly aged. Presidents have a demanding travel and meeting schedule and need to remain alert and focused, while at the same time keeping their eye on a multitude of issues. A younger person may be able to sustain this level of intensity longer, physically and mentally.
- Reform: A younger President may be less entrenched in the political machine and better able to bring in fresh, forward-thinking ideas.
- Legacy: Some of our former Presidents have gone on to make great contributions as peace negotiators, social activists, lecturers, and advisors. A younger President will have a longer post-Presidency to continue serving and influencing in strategic ways.
Cons of an Age Limit
- Experience: Putting younger people in charge means they simply don’t have as many decades of experience in politics or just in life itself. They may be idealistic in a way that is not practical or achievable. An older person knows how the game works and has accumulated a network of connections to get things done.
- Continuity: Having older generations in charge bridges the gap between the country’s past and future. An older person may have a greater appreciation for how some of our traditions and institutions have served the nation well in the past and should not be lightly brushed aside.
- Trust: An older person can at times inspire more trust in their competence than someone younger. Obviously, there are limits, and we are certainly nearing them in 2024. But in general, you don’t want a financial advisor, a doctor, or a President who looks like they arrived to work on a skateboard, right?
- Medical Technology: People did not live as long in the past as they do today, thanks to improvements in nutrition and medical technology. Research into cognitive-enhancing drugs is rapidly progressing. A hard cut-off date in the Constitution would be short-sighted if future Americans live much longer, healthier, and mentally sharper lives well beyond their 80s and 90s. Thus, the real issue may not be age as much as ability.
