One such effort, Primary Sinema PAC, launched on Thursday, announcing that it would raise money to fund grassroots groups in Arizona that can “hold Sinema accountable” and “lay the foundation for a successful primary campaign when a strong challenger emerges.”

“We fought tirelessly to elect Kyrsten Sinema in 2018,” said Alex Gomez and Tomas Robles, the co-executive directors of Living United for Change in Arizona, one of the groups slated to receive funding from Primary Sinema PAC.

“Sinema has proven time and time again that she doesn’t share these values, so it’s time to organize and replace her with someone who does,” they said.
