(AP) — Kentucky can't sustain the cost of expanded Medicaid enrollments under the federal Affordable Care Act and needs to cut the rolls, Republican gubernatorial hopeful James Comer said Monday while promoting his health care plan. Speaking to a group that included health care executives, Comer said if he's elected governor in November he would review eligibility standards for Kentucky's Medicaid, the government health insurance program for the poor and disabled. More than half a million people have signed up for health insurance through kynect, the state-run health exchange, but most of those Kentuckians have enrolled in Medicaid. Many recipients deserve the benefits, Comer said, but "able-bodied adults" have been added to Medicaid rolls as part of the expansion carried out by second-term Democratic Gov.
