Danielle Allen is a political theorist at Harvard University and a contributing columnist for The Post.

A few weeks ago, I argued that the likely Democratic nominee, Hillary Clinton should take up the theme that it’s time to make America fair, for everyone. Who doesn’t want fairness?, I asked. Women do; men do. Black, Latino, Muslim and white Americans all want fairness. Religious Americans want fairness, and so do gay, lesbian, bisexual and transgender Americans. Somewhere, in the murky complexity of seeking to build a world that’s fair for all, despite our powerfully competing claims, there is, I believe, a way forward.

I’ll stand by that advice.

From left and right, we hear that the political parties exercise their power in unfair ways. We hear complaints that the political system is rigged and that money buys power. So why don’t we citizens wrest control of the 2021 redistricting process from majority parties in our state legislatures? We might take as a model throughout our states the recent Ohio bipartisan redistricting amendment, passed overwhelmingly by voters. Its purpose is to charge a bipartisan commission with producing compact districts that don’t favor one or another party. Then we could have many more contested elections, and from that a healthier political system. This sort of process would make for a fair America.

From left and right, we hear choruses of frustration that the tax code is complex, convoluted and unfair to almost everyone in one way or another, except perhaps those who manage to dodge paying much at all by taking advantage of particularly valuable real estate tax loopholes. Is that why Donald Trump doesn’t want to release his tax returns? Is anybody else against a simple and fair tax code?

From left and right, we hear laments that educational opportunities are distributed unfairly. The left decries the reliance of much K-12 education on property tax funding. This policy ensures that the least advantaged students infrequently gain early access to the educational opportunities they need to have a fighting chance in a world with a shrinking middle class. On the other side, the right continues to decry affirmative action, even as that practice has receded considerably on college campuses. Perhaps if we could fund K-12 education decently, the left could say goodbye to affirmative action’s remnants. A compromise? What an idea. Recovering that art would make for a fair America.

From left and right, we hear complaints about the excessive use of governmental power, particularly in the judicial arena. Evidence abounds for the racial disparities in how we perpetually prosecute the war on drugs, even as Americans continue to consume $100 billion of illegal drugs each year. We hear of disproportionate penalties driving mass incarceration, of locales that harvest fines to raise revenue and incarcerate those who can’t pay fines, of the lifetime consequences of the diminished access to jobs and education that comes from a felony conviction for a minor offense. Could we end the hypocritical war on drugs and pursue broad reform in our criminal-justice system at the state as well as the federal level? That would be fair, and go well beyond what we all imagine possible.

Feisty readers have objected to my proposal that Clinton should take making America fair for all as her theme. My favorite argument against its persuasive value is that no one wants to get a rating of “fair” on a performance evaluation.

But look at it this way. If we could make America fair at last, we would in fact have exceeded expectations.

Readers who are focused on performance evaluations may think that the United States needs a formal job description. Well, America has one, and here it is: “We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.”

A more perfect union. Justice. Domestic tranquility. Those goals require establishing fairness at the heart of our laws, our political institutions and our social relations. In the current climate of hostility, polarization and mutual disdain, achieving that would be to exceed expectations by a very great distance.

As you consider your vote, ask yourself which candidate is committed to fairness for all. This is the only kind of candidate who has even a chance of meeting, let alone exceeding, our expectations. And in order to identify that candidate accurately, we the people will ourselves now also have to exceed expectations.
