The New York Times reports:

Five veterans tapped to advise Senator Kyrsten Sinema, an Arizona Democrat, resigned from their posts on Thursday, publicly accusing her of “hanging your constituents out to dry” in the latest sign of growing hostility toward a centrist who has emerged as a key holdout on President Biden’s agenda.

In a scathing letter obtained by The New York Times, the veterans took Ms. Sinema to task for her refusal to abolish the filibuster and her opposition to parts of Mr. Biden’s multitrillion-dollar social safety net, education, climate and tax plan, stances that have stymied some of his top priorities.

“You have become one of the principal obstacles to progress, answering to big donors rather than your own people,” the veterans wrote in a letter that is to be featured in a new advertisement by Common Defense, a progressive veterans’ activist group that has targeted Ms. Sinema.

“We shouldn’t have to buy representation from you, and your failure to stand by your people and see their urgent needs is alarming,” they added.

The resignations add to a crescendo of anger and pressure that Ms. Sinema is facing from erstwhile allies who say they are perplexed by her recent tactics. She has resisted major elements of Democrats’ sprawling social safety net and climate bill, including raising individual income and corporate tax rates to pay for it. Because Democrats control the Senate with only 50 votes, even one defection could spell defeat for the measure, giving Ms. Sinema outsize influence to determine what can be included.
