Nathan Newman thinks the health care bill will destroy the conservative movement "[b]ecause trying to repeal it will tear the movement apart and it will be the platform to destroy conservative anti-tax politics."
The Randian/Soylent Green faction of the capitalist ruling class hated social security too, and that didn't destroy their movement. The Randian faction doesn't need either social security or universal health care to go away, they need it to not expand, and to the extent that it does expand, the expansion needs to be under the direct control of the capitalists, not the government. They're not sadistic, they're just indifferent to the well-being of the people.
Their primary goal is to preserve and enhance their power and privilege as a ruling class. The health care bill as it exists today does little to diminish their power and privilege, and may (as Robert Reich notes) actually enhance it. Their goal, which is largely complete, is to destroy Keynesian economics (and its advocates in the Democratic party), which supports the economic demand of the working and middle classes.
Liberals and progressives — even smart ones — are just as capable of wishful, magical thinking as any Christian.
