In addition to Indivisible, liberal groups like the Working Families Party are planning to target the 10 House Democratic moderates who insisted that they would not support the social spending plan until House leadership committed to the September 27 vote. Natalia Salgado, director of federal affairs for the Working Families Party, said that the group would knock on doors, publish op-eds, hold virtual town halls in the members’ districts, purchase six-figure ad buys and mount local media blitzes. The organization is also speaking with potential 2022 primary challengers in some of the Democrats’ districts.

“In places where it is a solid blue district, we need people there who elected these folks to Congress to know to come together and be informed about how their representative is usurping their ability to get what they need,” Salgado said. “We’re definitely going to be jumping in some of these races to be able to challenge some of these ten.”

In addition to events and ads, progressives are trying to increase momentum for the package through polling. Real Recovery Now!, a coalition of progressive and labor groups, plans to release polls in mid-September from 12 states on the package’s provisions, according to a spokesperson.
