More  than any of the other candidates who vied for the presidency during this too-long campaign, Republican Donald Trump and Democrat Bernie Sanders tapped into the frustrations of the nation’s working class. While Sanders succumbed to a Democratic primary process that favored the establishment candidate, Hillary Clinton, Trump was able to emerge from a large field of Republicans and the absence of “super delegates” to emerge with the nomination.

On Tuesday, Trump’s working-class appeal cut a wide swath through the rust belt states of the Midwest and led to his solid Electoral College victory, even as it appeared Clinton was emerging with the most popular votes. She thus becomes the second Democrat in 16 years to lose the presidency in that manner.

Trump does not have a mandate. But he is the president-elect. Now the task of addressing that working-class anger, delivering on the promise of restoring blue-collar jobs, and providing for the nation’s security fall to him. With his party in control of both the House and Senate, he will have all the levers necessary to pursue his agenda. For the good of a nation, we wish him well.

But we cannot ignore the concerns that led us to reject him in both the primary and general election and to endorse his far more experienced opponent. But in 2016, experience was a liability. In a time when many in the nation sought change, Clinton was a candidate tied to the past and to powerful interests that many in the middle class blame for their economic stagnation and the transference of wealth to the 1 percent investment class.

If a Trump administration actually pursues the economic policies on which he campaigned — massive tax cuts and the rejection of free trade agreements unless they can be renegotiated in the nation’s favor — it will explode the deficit and set off trade wars that could cause another global recession.

Trump has promised repeal of the Affordable Care Act — Obamacare — a goal of the Republican Party since its passage in President Obama’s first term. But to be replaced by what? Republicans have never adequately supplied that answer. The insurance industry, after adjusting to the mandates of the act, would again be forced to adjust to a new reality. We saw repairing the act and moving forward as the more appropriate avenue, but — through the Electoral College — voters chose a different route.

Trump’s promised appointment of staunch conservatives to the U.S. Supreme Court will lock in place the dreadful Citizens’ United decision that has allowed big money to corrupt our political process. Threatened are civil liberties that millions have taken for granted. Yet to the victor goes the appointing power. We urge Democrats in the Senate not to follow the lead of the Republicans and obstruct, but instead act fairly on Trump’s judicial nominations and consent to qualified appointees.

Though it may disappointment many of his legion, the next president needs to reconsider some of his most divisive policy planks.

Creating deportation teams to round up immigrants who came to the country outside the legal process, and undertaking mass deportation, would be a scene more reminiscent of past fascist regimes than in tune with American ideals. Our next president would be better off focusing on true criminals who are in this country illegally.

Building a massive wall on the southern border is an absurdity and would be a waste of the nation’s treasure, as well as a sign of ill-will toward a neighbor and ally. Perhaps Trump will move from bombast to reality by improving security along the border, without a wall.

Our next president has said he wants to reopen coal mines, boost the use of fossil fuels and dismissed the threat posed by climate change. Without U.S. leadership on this issue, recent agreements to curb greenhouse gas emissions could crumble, with disastrous consequences.

Likewise, moving to an isolationist, America-first foreign policy would be to ignore the lessons of the past. When the United States detaches, global fault lines can more easily shift. In history that has led to great wars the U.S. could not avoid. We urge our president-elect to keep our alliances strong.

Perhaps Trump will moderate from the rhetoric that led to his ascension to the highest political office. Democrats, with strong minority standing in the Senate, should be willing to work with Trump on reasonable policy proposals, even those outside their party’s ideology. He and the Republicans won.

But if Trump’s governance matches his most radical rhetoric, then the nation has made a grave mistake and the Democratic minority must do all it can to mitigate the damage. The nation should know soon enough what man it elected president.
