Should The Voting Age Be Raised To 21

The Voting Age Debate: Why Raising It to 21 Might Be a Terrible — or Brilliant — Idea

Here's the thing about turning 18: in most countries, it comes with a sudden bundle of new rights and responsibilities. You can be drafted into military service. You can vote. But in the United States, you still can't buy alcohol until 21. This leads to you can sign contracts. So why does 18 feel like a magic number for civic duty, but not for drinking a beer?

That contradiction sits at the heart of one of the more persistent debates in American democracy: should the voting age be raised to 21? It's not just a question of brain science or legal consistency — it's a question of who we think deserves a voice in shaping the country they'll inherit.

What the Voting Age Actually Means

The 26th Amendment, ratified in 1971, lowered the voting age from 21 to 18. Vietnam was ending, but the principle stuck. Worth adding: the reasoning was straightforward, if morally urgent: if you're old enough to be drafted and sent to war, you're old enough to have a say in whether that war should happen. Eighteen-year-olds gained the right to vote in every state.

But here's what's interesting — the debate never really went away. It just shifted. And in recent years, lawmakers in several states have proposed raising the voting age back to 21. Not because they think 18-year-olds are inherently irresponsible, but because they're questioning whether the line at 18 makes sense anymore.

The Case for Keeping It at 18

Proponents of keeping the voting age at 18 argue that the right to vote shouldn't be conditional on maturity benchmarks that are, frankly, subjective. Day to day, eighteen-year-olds pay taxes, serve in the military, and make major life decisions. Denying them the vote because we think they might not be "ready" feels paternalistic — and historically, that kind of paternalism has been used to justify restricting voting rights across all kinds of lines.

There's also the practical argument: young people are already engaged. Many of them understand politics better than some adults twice their age. They organize protests, lobby for climate action, and mobilize around issues like gun control and student debt. Why gatekeep their participation?

The Case for Raising It to 21

Those who favor raising the voting age to 21 often point to neuroscience. The prefrontal cortex — the part of the brain responsible for decision-making, impulse control, and long-term planning — isn't fully developed until the mid-20s. That's not a judgment on 18-year-olds; it's just biology.

But beyond brain scans, there's a cultural argument. In most other contexts — buying alcohol, renting a car, entering into certain contracts — 21 is the threshold. If we treat 21 as the age of full legal adulthood in so many other areas, why not voting?

Some also argue that raising the voting age could reduce the influence of transient opinions. Their priorities can shift rapidly. Still, is that a bad thing? Now, college students, for instance, often move frequently and may not follow local elections closely. Maybe not — but it's worth considering.

Why This Debate Matters More Than Ever

The voting age isn't just a legal technicality — it's a statement about who belongs in the democratic process and who doesn't. Every time we draw a line around who can vote, we're making a choice about what kind of democracy we want.

Consider this: young people are already the most likely demographic to support progressive policies like climate action, tuition-free college, and criminal justice reform. If the goal of raising the voting age is to reduce their political influence, that's a transparent power play. If the goal is to ensure more informed voting, that's a different conversation entirely.

But here's what makes this debate particularly relevant now: trust in institutions is declining across all age groups, not just among young people. Because of that, engagement isn't the problem. Worth adding: voter turnout among 18- to 29-year-olds actually increased in the 2018 and 2020 elections. Whether that engagement translates into informed decision-making is a separate question — and one that's hard to measure.

The Military Exception

One of the most compelling arguments against raising the voting age is the military exception. We send them to war, but we don't let them drink. If 18-year-olds can be drafted, they should be able to vote. But that argument also reveals something deeper: we already treat 18-year-olds as adults when it's convenient. Period. We let them vote, but we don't always listen to what they say.

Raising the voting age to 21 without also reconsidering the draft would create a new inconsistency — one that's harder to justify than the current one.

How the Brain Science Actually Works

Let's talk about what neuroscience really says. But that doesn't mean 18-year-olds are incapable of reasoning, critical thinking, or understanding complex policy issues. Yes, the prefrontal cortex continues developing into the mid-20s. What it means is that they're still learning to weigh long-term consequences against immediate rewards — a skill that takes time to develop for everyone, not just young people.

More importantly, brain development varies widely from person to person. Some 18-year-olds are more mature than some 25-year-olds. Using age alone as a proxy for decision-making ability is imprecise at best.

And here's a nuance that often gets lost: political engagement itself may accelerate brain development. When young people are encouraged to participate in democracy — to research candidates, debate issues, and vote — they're exercising the very skills that neuroscience says are still developing. Restricting that participation could actually hinder development, not protect against poor decisions.

The Experience Factor

There's also the question of lived experience. They've had to grow up fast. This leads to eighteen-year-olds have lived through events that older generations didn't — mass shootings, climate anxiety, economic instability, a global pandemic. Does that make them more or less qualified to vote? It depends on who you ask.

But it does suggest that maturity isn't just about age — it's about context. And today, 18-year-olds may be more politically aware than previous generations were at the same age, simply because they've had to be.

What Most People Get Wrong About This Debate

Here's what I think gets missed in most discussions of the voting age: the assumption that this is primarily a question of competence. It's not. It's a question of values.

When someone says 18-year-olds aren't ready to vote, what they're often really saying is that they don't want 18-year-olds to have political power. And that's a legitimate thing to debate — but it should be framed as a values question, not a scientific one.

Similarly, when someone says raising the voting age would improve the quality of elections, they're making a claim about which voices matter more. That's not wrong — it's just not neutral.

The Turnout Reality

Another thing people get wrong: the idea that young people don't vote. In practice, in 2020, nearly half of eligible voters aged 18 to 29 cast ballots. That's higher than in many previous cycles. And in 2018, young turnout was the highest it had been in decades.

If the concern is that young people aren't engaged, the solution isn't to restrict their access to the ballot box — it's to make voting more accessible. Automatic voter registration, expanded early voting, and campus polling locations have all been shown to increase youth participation.

What Actually Works: Practical Ideas

If we're serious about improving democratic participation — regardless of where we land on the voting age — there are concrete steps we can take.

Make Registration Easier

Automatic voter registration has been implemented in over a dozen states. Practically speaking, when you get or renew your driver's license, you're automatically registered to vote unless you opt out. This doesn't require changing the voting age — it just removes barriers to participation.

Expand Access to Polling Places

College campuses, in particular, often lack convenient polling locations. Some states have laws requiring universities to provide space for polling places. Still, others don't. The difference is measurable: campuses with on-site polling see significantly higher turnout among student voters.
