Changes made to an Obamacare repeal bill that are aimed at appeasing conservatives would cut the deficit reduction in the bill by more than half, from $337 billion saved over the next decade to $150 billion, according to the Congressional Budget Office.

That’s a 55 percent cut in deficit savings from the original version, CBO said. The score also predicted there would be little change to the uninsured, as the original estimate found that 24 million people could go without insurance over next decade.
