On the surface, the coronavirus pandemic seems to have driven already-divided Americans even further apart.

Police brutality has triggered violent protests in dozens of cities. In a split that's been dubbed the "lockdown left" versus the "reopen right," Democrats are bickering with Republicans over whether public health or the economy should come first. In the House, GOP lawmakers have sued Democrats for permitting proxy voting during the pandemic. And President Trump is stoking all these divisions as the defining strategy of his reelection campaign.

"The unity that was created during and after world wars for America lasted years, the unity after 9/11 lasted months — and the unity during this Covid crisis might be days," says former Rep. Tim Roemer, an Indiana Democrat who helped spearhead a recent bipartisan letter signed by 110 former lawmakers, top government officials and governors urging Congress to respond with more strength, unity and cooperation.

But the rancor and bad blood roiling government officials are not the whole story.

Americans are also reporting heightened public unity and trust as communities draw together in the crisis. A survey last month by More in Common found 90 percent saying "we're all in it together," compared to only 63 percent in 2018. The number who described the country as unified jumped eightfold in the same period.
