Union leaders told the Senate Democrats' campaign arm in a private call not to expect them to back lawmakers in upcoming elections unless they coalesce behind the pro-labor Protecting the Right to Organize Act, three sources told Politico.
One lawmaker, in particular, became the center of attention, two sources said: Sen. Mark Kelly (D-Ariz.), one of only three senators in the majority who have yet to sign onto the PRO Act and who is expected to face a tough reelection battle next year.
Arizona’s Kyrsten Sinema and Virginia’s Mark Warner have also not backed the measure. The package thus far has 47 Senate cosponsors 45 Democrats, two independents leaving it well short of the 60 “yes” votes needed to overcome the filibuster. But unions see it as a litmus test.
