The legislation the Senate Finance Committee is expected to approve calls for the biggest expansion of Medicaid since its creation in 1965. Under the Senate bill and a similar House proposal, a patchwork state-federal insurance program targeted mainly at children, pregnant women, and disabled people would effectively become a Medicare for the poor, a healthcare safety net for all people with an annual income below $14,404, reports the Washington Post. Whether Medicaid can absorb a huge influx of beneficiaries is a matter of concern to many governors, who have cut low-income health benefits to cope with the economic downturn.
