Every tedious old argument in the world is being regurgitated lately in service of the final, desperate defense of the Republican health care bill. The latest hotness is the old “we’re not cutting, we’re just slowing the rate of growth” argument for Medicaid. So let’s make this easy.

The CBO estimates that the reduced spending will result in 15 million fewer people receiving Medicaid. Unsurprisingly, that’s a reduction of about 18 percent. It’s pretty simple.
