Inside the last-minute political breakdown that doomed the Clarity Act vote

Senator Cynthia Lummis' disappointment was already palpable the day before the U.S. Senate shot down the Digital Asset Market Clarity Act. She stood on a stage at a crypto event in Washington and talked about how she'd worked on the bill for more than five years — the bulk of her career as a senator.

Lummis, who is retiring soon, knew by then that things were going badly. She and other Republicans had made what they characterized as their final offer, which they argued carried more concessions to Democrats, including another agreement from President Donald Trump to accept unprecedented ethics constraints on his crypto holdings. But Democrats were already rebuffing it and coming out with more demands.

From the other side, the Democrats saw legislation that they argued was substantially similar to what was already on the table and still let Trump evade real responsibility for conflicts of interest in controlling a crypto empire while also steering its oversight. That didn't really have much to do with the actual crypto market structure policies at the heart of the bill, but it's the issue they circled their wagons around.

"The president should not be able to use the power and influence of his office to benefit his own crypto holdings while his administration makes decisions that could directly affect their value," said Senator Mark Warner, one of the Democrats who worked on the illicit-finance portions of the bill and said he really wanted to vote yes on it. "At a minimum, any serious crypto legislation must include meaningful ethics requirements that prevent the president and other senior government officials from profiting off the policies they oversee."

But the Democrats said they were making an effort to continue talks down to the wire, and they were rebuffed by Republicans who shut down the negotiation and proceeded with the vote. (The vote didn't have to happen on Tuesday afternoon, and it could have been shifted by Republican leaders if there were still a chance for negotiations.)

"Just as Democrats and Republicans were making progress to address ethics concerns, Republican leadership ended talks and forced a vote," said Democrat Senator Ruben Gallego in a statement after the Tuesday vote. "They were never serious about bipartisan negotiations."

Senate Minority Leader Chuck Schumer told reporters much the same on Tuesday.

“As you may have heard, there was a bipartisan deal on the table as recently as this afternoon to resolve all outstanding items including ethics," Schumer said. “Republican leadership walked into the room, broke up the bipartisan discussion and said, 'No, we’re done' and killed it."

So the Democrats — even those like Senator Kirsten Gillibrand that had pushed for the crypto bill since its beginnings — jumped ship, leaving a meager showing of 49 votes in support. That's 11 less than the 60 to clear the minimum hurdle for advancing the bill.

For her part, Lummis argued that the counter offer she saw from Democrats on Monday was essentially the same position they'd taken before the Senate left on its August recess.

And in a statement after the vote, she blamed the Democrats, calling them "anti-American" (despite the fact that a handful of the no votes came from her fellow Republicans).

"This afternoon, Senate Democrats proved they were never truly serious about protecting consumers and preserving American leadership," she said. "I sat at the table with Senate Democrats working in good faith to get this done while they played games."
