There was a conspiracy unfolding behind the scenes, one that both curtailed the protests and coordinated the resistance from CEOs. Both surprises were the result of an informal alliance between left-wing activists and business titans. The pact was formalized in a terse, little-noticed joint statement of the U.S. Chamber of Commerce and AFL-CIO published on Election Day. Both sides would come to see it as a sort of implicit bargain–inspired by the summer’s massive, sometimes destructive racial-justice protests–in which the forces of labor came together with the forces of capital to keep the peace and oppose Trump’s assault on democracy.

The handshake between business and labor was just one component of a vast, cross-partisan campaign to protect the election–an extraordinary shadow effort dedicated not to winning the vote but to ensure it would be free and fair, credible and uncorrupted. For more than a year, a loosely organized coalition of operatives scrambled to shore up America’s institutions as they came under simultaneous attack from a remorseless pandemic and an autocratically inclined President. Though much of this activity took place on the left, it was separate from the Biden campaign and crossed ideological lines, with crucial contributions by nonpartisan and conservative actors. The scenario the shadow campaigners were desperate to stop was not a Trump victory. It was an election so calamitous that no result could be discerned at all, a failure of the central act of democratic self-governance that has been a hallmark of America since its founding.

Their work touched every aspect of the election. They got states to change voting systems and laws and helped secure hundreds of millions in public and private funding. They fended off voter-suppression lawsuits, recruited armies of poll workers and got millions of people to vote by mail for the first time. They successfully pressured social media companies to take a harder line against disinformation and used data-driven strategies to fight viral smears. They executed national public-awareness campaigns that helped Americans understand how the vote count would unfold over days or weeks, preventing Trump’s conspiracy theories and false claims of victory from getting more traction. After Election Day, they monitored every pressure point to ensure that Trump could not overturn the result. “The untold story of the election is the thousands of people of both parties who accomplished the triumph of American democracy at its very foundation,” says Norm Eisen, a prominent lawyer and former Obama Administration official who recruited Republicans and Democrats to the board of the Voter Protection Program.

For Trump and his allies were running their own campaign to spoil the election. The President spent months insisting that mail ballots were a Democratic plot and the election would be “rigged.” His henchmen at the state level sought to block their use, while his lawyers brought dozens of spurious suits to make it more difficult to vote–an intensification of the GOP’s legacy of suppressive tactics. Before the election, Trump plotted to block a legitimate vote count. And he spent the months following Nov. 3 trying to steal the election he’d lost–with lawsuits and conspiracy theories, pressure on state and local officials, and finally summoning his army of supporters to the Jan. 6 rally that ended in deadly violence at the Capitol.

The democracy campaigners watched with alarm. “Every week, we felt like we were in a struggle to try to pull off this election without the country going through a real dangerous moment of unraveling,” says former GOP Representative Zach Wamp, a Trump supporter who helped coordinate a bipartisan election-protection council. “We can look back and say this thing went pretty well, but it was not at all clear in September and October that that was going to be the case.”
