The expansion of Medicaid and insurance subsidies through the ACA meant 20.4 million more people had health insurance in 2016 than in 2010. According to the non-partisan Congressional Budget Office, somewhere just north of 20 million Americans would lose health insurance in the various repeal-and-replace scenarios that have been floated of late and rejected, for now. That number jumps to 30 million-plus if Obamacare is simply repealed.
What all proposed ACA-repeal legislation has in common is deep cuts to Medicaid. Indeed, the group most affected by any of the bills is poor Americans who receive Medicaid support.
