Never heard of this. But it's their right not to back her any longer. But when her and Manchin join the Repubs... there will be plenty of $$ floating her way.

Emily's List, the largest financial contributor to Sen. Kyrsten Sinema's campaign for office, is threatening to cut off its support of the Arizona Democrat if she keeps refusing to agree to change the Senate's filibuster rules in a push to pass the party's voting legislation.
"We want to make it clear, if Sen. Sinema cannot support a path forward for the passage of this legislation, we believe she undermines the foundations of our democracy, her own path to victory and also the mission of Emily's List, and we will be unable to endorse her moving forward," Laphonza Butler, the organization's president, said in a statement Tuesday, reports The Washington Post.
