We will flex our muscles at the ballot box, too. Many high school seniors will cast their first ballots this November, and in 2020, a majority of today’s high school students will most likely be able to vote in their first presidential election. And we will not forget the elected officials who turned their backs on their duty to protect children.

Let us remind politicians like Donald Trump, Paul Ryan and Mitch McConnell who accept donations from the National Rifle Association and oppose efforts to restrict gun purchases that we are the future leaders and voters of this country. Let us remind corporations like FedEx that provide discounts to N.R.A. members that we are their future customers.

The Stoneman Douglas students who began speaking out after the killings last month have better articulated the need for common-sense gun control laws and school safety than our elders ever have. But those students cannot do it alone. We as a generation must band together behind them, just as Alexander Hamilton, James Madison, Thomas Jefferson and others stood behind George Washington and fought to create this great country.

We applaud many of the elected officials who have said they will work to reduce gun violence in their states. We hope Gov. Phil Murphy of New Jersey, our home state, will work with us and other advocates to do the same. We also support companies like Dick’s Sporting Goods, Avis Budget Group, Hertz, Delta, United and Walmart, which have stood behind the principles of the March for Our Lives movement and either cut ties with the N.R.A. or changed their policies on firearms sales.

On March 24, hundreds of thousands of children and teenagers nationwide will participate in March for Our Lives. We are among the 19 students helping organize New Jersey’s march, which will take place in Newark, a city with far too much gun violence. We implore students, their parents, teachers, school administrators, religious leaders, corporate executives and elected officials across the country to join any march, no matter where they are, and fight to make our schools safe.
