The Mississippi Economic Policy Center, to whom I have linked many times, has some excellent analysis of the effects of the proposed Medicaid expansion. Here are three posts to read to help combat the GOP hype machine, which is stuck in overdrive on this issue:
4 Reasons why Medicaid Expansion is Good for Mississippi’s Economy
Rejecting Medicaid Expansion would create coverage gap for Mississippi’s most Vulnerable Working Families
Health Care Jobs become Critical to Mississippi’s Economy
The bottom line is that the federal government is looking to pump money into a vital portion of Mississippi's economic equation, and we'd be foolish to refuse it.
