Sexual boasting, emails, tax returns, deplorables — the second presidential debate Sunday featured insults wrapped up in put-downs. This debate was held within miles of Ferguson, Mo., but it was never mentioned. The citizens offered questions about issues — health care, the U.S. Supreme Court, energy. The moderators peddled scandals — and elicited insults.

Some things are clear. Republican presidential candidate Donald Trump has no clue how insulting he is when he makes his brazen appeal to African-American and Latino voters, promising to “do things that haven’t been done, including fixing and making our inner cities better for the African-American citizens that are so great, and for the Latinos, Hispanics, and I look forward to doing it.”

That’s great, but Mr. Trump has offered no plan to accomplish this. He asks us only to trust him. But someone who has fanned the flames of racial resentment, trashed Mexicans and Muslims and insulted women during his campaign is not exactly a person to gain a lot of trust.

Democratic presidential candidate Hillary Clinton promises to be the president of all of America. And she offers real plans. She would raise the minimum wage and make college tuition free for all but the rich. She calls for a major plan to rebuild America, investing in infrastructure, schools and water systems. That will put people to work in good jobs and make our cities better.

Mrs. Clinton also has embraced Rep. James Clyburn’s 10-20-30 pledge to invest 10 percent of federal contracting in communities comprising 20 percent of the nation’s population that have been below the poverty line for 30 years. That would help both white, rural communities and urban ghettos and barrios. Mrs. Clinton isn’t just saying trust me; she’s laying out plans that could make a difference.

But what the debate made clear is how important it is for the people to set the agenda after the election. Voting is vital but not sufficient. What we do can change the national agenda and force action.

When Dwight D. Eisenhower was elected president, he did not have any thought about using federal troops to desegregate schools in Little Rock, Ark. The movement forced that on his agenda. President John F. Kennedy had no commitment to ending segregation of public accommodations; the Civil Rights Movement forced that onto his agenda. President Lyndon B. Johnson thought continuing the war in Vietnam would protect him politically. The anti-war movement changed that calculation.

Today, Black Lives Matter has forced criminal justice reform onto the agenda of both parties. The Fight for $15 has pushed minimum wage hikes in cities across the country. Immigration reform is part of Mrs. Clinton’s first 100-day plan because citizen movements have forced it there.

The next president will make fateful decisions about war in the Middle East, how to get the economy moving, U.S. Supreme Court nominees, getting health care costs under control, climate change, growing, unsustainable and extreme inequality, and reviving the Voting Rights Act.

We can’t afford to leave these choices to the next president, no matter who is elected. We can’t let a Congress corrupted by big money and entrenched lobbies set the agenda.

Citizens in motion must force the vital and the just onto the next president’s and the next Congress’ agenda. We will decide by what we do, or by what we decide not to do. One thing is clear from the debate Sunday night: It is time to organize.
