“This is our moment to deliver on all of the promises that we made,” said Emily Kirkland, the executive director of Progress Arizona. “She is just absolutely standing in the way of that, without making clear what she wants.”

Kirkland, who often spent 13-hour days campaigning for Sinema three years ago, now feels “incredibly frustrated” with the senator’s hesitation to go along with her party on a major $3.5 trillion spending bill that Democrats hope to pass to enact a wide range of key liberal priorities…

Brianna Westbrook, a progressive voter and a precinct captain in Arizona, reflected on Sinema’s career while standing outside on the patio of The Main Ingredient in Phoenix, a restaurant close to Sinema’s former congressional district.

“She’d never been in the majority. She is now,” said Westbrook, who also campaigned for Sinema in 2018. “And she has shown that she cannot lead when her party is the majority.”

Westbrook said she and other voters who supported Sinema now feel betrayed. “She’s used everybody as a ladder to climb to a position of power.”
