WaPo:

The ads on Facebook sounded populist and passionate: “The people are rising up against these insane shutdowns,” they said. “We’re fighting back to demand that our elected officials reopen America.”

But the posts, funded by an initiative called “Convention of States,” were not the product of a grass-roots uprising alone. Instead, they represented one salvo in a wide-ranging and well-financed conservative campaign to undermine restrictions that medical experts say are necessary to contain the coronavirus — but that protesters call overkill and whose economic fallout could damage President Trump’s political prospects.

A network of right-leaning individuals and groups, aided by nimble online outfits, has helped incubate the fervor erupting in state capitals across the country. The activism is often organic and the frustration deeply felt, but it is also being amplified, and in some cases coordinated, by longtime conservative activists, whose robust operations were initially set up with help from Republican megadonors.

The Convention of States project launched in 2015 with a high-dollar donation from the family foundation of Robert Mercer, a billionaire hedge fund manager and Republican patron. It boasts past support from two members of the Trump administration — Ken Cuccinelli, acting director of U.S. Citizenship and Immigration Services, and Ben Carson, secretary of housing and urban development.
