I think you underestimate the stupidity of the average American voter. I fear that once they Democrats touched this thing focusing on the healthcare issue, they opened themselves up for the argument that they partially own it (which the Rs will absolutely push next fall). At this point, I think the Dems have to go all in and make the Republicans eliminate the filibuster and cram this thing through. That would be awful for the folks relying on the subsidies, but would allow (1) the Dems to look like they were actually fighting for everyone and (2) MAGA to finally touch the stove and feel the pain. That's why the Republicans are absolutely not going to make that move. Even if the Rs actually concede, the Dems will not benefit much, if at all - see opening premise. Politically, I think tying this to healthcare was a stupid move; morally right, but stupid if they're trying to stop the country's march to authoritarianism.
