Kyrsten Sinema Is the Final Holdout on Democrats’ Climate Deal

Kyrsten Sinema Is the Final Holdout on Democrats’ Climate Deal 1

Now that Senator Joe Manchin III of West Virginia is on board, the Arizona Democrat has emerged as the final holdout on Democrats’ domestic agenda. So far, she’s staying characteristically silent.

WASHINGTON — As Senator Kyrsten Sinema, Democrat of Arizona, took her turn presiding over the Senate floor on Tuesday, Senator Joe Manchin III of West Virginia, a fellow Democrat, got down on one knee beside her at the dais, leaning in intently to speak to her in hushed tones.

Ms. Sinema, an inscrutable lawmaker who has shown a willingness to buck her party, had replaced Mr. Manchin as the most prominent and speculated-upon holdout on his party’s major climate, energy and tax package, and the West Virginian was there to lobby her to support it.

With journalists watching from the gallery above, leaning in to try to hear the conversation, Ms. Sinema waved in apparent acknowledgment.

“She’ll make a decision based on the facts,” Mr. Manchin told reporters later, calling it “a good talk.”

While Mr. Manchin has embraced the public scrutiny and attention that comes with being a swing vote in the evenly divided Senate, Ms. Sinema has remained a tight-lipped enigma. Passage of Democrats’ major domestic policy initiative, negotiated by Mr. Manchin and Senator Chuck Schumer of New York, the majority leader, now hinges on whether she is willing to support it.

So far, Ms. Sinema won’t say.

It has put Democrats in a perilous position as they rush to move the package forward as early as this week and toil to unite all 50 members of their caucus behind it. Republicans are expected to unanimously oppose the plan, which includes hundreds of billions of dollars in energy and climate proposals, tax increases, extended health care subsidies and a plan aimed at lowering prescription drug prices, meaning Democrats cannot spare a single vote if all Republicans are present.

Party leaders will also have to maneuver the bill through a series of rapid-fire amendments that could pass if any Democrat joins Republicans in support. With Mr. Manchin enthusiastically embarking on a media tour to celebrate the measure, fears of failure were now being fueled by Ms. Sinema’s characteristic silence.

A spokeswoman for Ms. Sinema has said that the senator was reviewing the legislation and waiting for guidance from top Senate rules officials, who were analyzing whether it meets the strict rules that apply under the budget reconciliation process. Democrats were using the reconciliation process to shield the legislation from a filibuster and speed it through Congress.

Top Democrats on Wednesday were quietly weighing what potential changes to the bill, particularly to its tax provisions, might be needed to win Ms. Sinema’s support, as the Arizona senator was preparing her own wish list.

While she voted for the initial $3.5 trillion budget blueprint that allowed Democrats to begin work on the legislation, Ms. Sinema has not offered explicit support for many pieces of the current package, most notably much of the tax increases included to pay for it. Doubt about Ms. Sinema’s support has centered on her past opposition to a proposal aimed at limiting the carried interest preferential tax treatment for income earned by venture capitalists and private equity firms. A similar proposal was among the tax changes Mr. Manchin and Mr. Schumer included in their deal.

Mr. Manchin and other Democrats have said the provision would ensure fairness in the nation’s tax code. But Ms. Sinema, who resisted many of the tax rate increases her colleagues had pushed for, has privately signaled she wants the carried interest measure removed.

She is also pushing to add funds for drought resiliency, given that her state has struggled with devastating water shortages, according to officials briefed on the discussions, who spoke on the condition of anonymity to disclose sensitive negotiations. Politico first reported the request from Ms. Sinema, whose state is currently in its 27th consecutive year of drought, according to the state’s climate office.

Ms. Sinema, like most of her colleagues, was blindsided by news of the deal between Mr. Manchin and Mr. Schumer and its details. Mr. Manchin has said that he intentionally did not confide in or consult other Democrats during final negotiations to salvage the climate and tax proposals because, he told reporters on Monday, “I wasn’t ever sure that we would get to a finale, to get a completed bill.”

Speaking to a West Virginia radio station on Tuesday, Mr. Manchin noted that Ms. Sinema had played an outsized role in shaping the prescription drug proposal and scaling back Democratic ambitions to overhaul the tax code as part of the plan.

It was unclear whether Democrats would be willing to strike the tax break for wealthy executives altogether to win over Ms. Sinema. Estimates suggest it would raise about $14 billion, a small portion of the $740 billion plan.

“It may strike some people in Washington as old-fashioned, but in my experience, Senator Sinema has always believed you must be thoughtful and cautious when it comes to changing tax policy,” said John LaBombard, a senior vice president at the public affairs firm ROKK Solutions, who left Ms. Sinema’s office in February after more than three years working in her office.

Party leaders expressed guarded optimism that they could pass the package with its key elements intact.

“I’m very hopeful we’re all going to be united and pass this bill,” said Mr. Schumer, who said he and his staff were in touch with Ms. Sinema about the measure.

Others avoided even commenting on whether they had spoken to Ms. Sinema.

“Why would I be sharing that with any of you guys at this point?” Senator Mark Warner of Virginia asked, throwing his arms up in the air with a grin as he climbed onto the Senate subway.

Ms. Sinema, 46, has toggled between vexing her party with her refusal to embrace some of its top priorities and playing a key role in negotiating some of its hardest-won bipartisan compromises.

She has drawn ire from her colleagues and some voters for opposing their push to undo the 60-vote filibuster threshold that Republicans have used to block much of the Democratic agenda. Ms. Sinema also joined Mr. Manchin in helping to hammer out the bipartisan $1 trillion infrastructure law, and played a leading role in forging a compromise on gun safety efforts that yielded the first significant federal law on that issue in decades.

She has previously expressed support for investing in climate change, leaving many Democrats hopeful that she will choose to back the final deal. On the Senate floor on Tuesday, lawmakers in both parties made a point of chatting her up in between votes.

Ms. Sinema is also hearing directly from voters, activists and local businesses in her state.

Daniel Seiden, the president and chief executive of the Arizona Chamber of Commerce and Industry, said in an interview that he and several business and industry representatives spoke with Ms. Sinema about the legislation for about 20 minutes on Tuesday, after reaching out to her office. They expressed concerns with how a proposed 15 percent minimum tax on corporations was structured, he said.

Ms. Sinema, Mr. Seiden recalled, asked for details about how businesses would be affected and whether the proposal “could be written better.” But, he added, she “didn’t tip her hand one way or another.”

Ms. Sinema, who faces re-election in 2024, is also facing a likely primary opponent as part of the backlash for her resistance to ending the filibuster. The Primary Sinema Project, a political group aimed at ousting her, warned that Ms. Sinema “better not mess this up” after the deal was announced, while Representative Ruben Gallego, a potential challenger and prominent critic, charged she was holding up the measure “to try to protect ultra rich hedge fund managers so they can pay a lower tax.”

Her Republican allies and business groups see Ms. Sinema as a last opportunity to derail a measure they have condemned as harmful to the nation’s economy. Americans For Prosperity, a conservative nonprofit advocacy group with ties to the Tea Party and the Koch Brothers, circulated an online ad against the legislation that pleaded “Come on Kyrsten … Say NO for Arizona.”

But her colleagues conceded that Ms. Sinema has seldom seemed swayed by the heat of public campaigns.

“She’s analyzing it, keeps her own counsel, I think as most of you know, and usually comes to her own decisions, pretty independent of any pressure that she might get from either side,” Senator John Thune of South Dakota, the No. 2 Republican, told reporters on Monday. “So, you know, I think she’s going through that process right now.”
