There were many conductors in the derailment of the crypto industry's Clarity Act

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.
