Obama passed medicare for all up to 138% of the poverty level.Let us know when Biden comes anywhere close to cutting the uninsured rate in half.
First, it's medicaid and not medicare.
Second, millions would still be uninsured even if the 12 states adopted medicaid eligbility.
The Affordable Care Act (ACA) allows states the option of expanding Medicaid coverage for people under age 65 to 138 percent of the federal poverty level (FPL) ($17,774 for an individual and $36,570 for a family of four in 2021).1 As of this writing, 12 states have neither expanded Medicaid nor passed ballot initiatives to expand Medicaid as allowed by the ACA. We project that there will be 14.6 million uninsured,2 of whom 5.8 million are below 100 percent of FPL in these 12 states in 2022.3
