Maine Republicans, like those in many other states, rabidly oppose expanding Medicaid under the President's Affordable Care Act. So a recent study by the non-partisan Kaiser Family Foundation (and confirmed by the conservative Heritage Foundation), which found that "Maine would save $690 million over the next 10 years if the state expanded eligibility," is a serious political problem for them. It's so much of a problem, in fact, that "Republicans have since attempted to discredit the study" by claiming "that the study is based on every state participating in expansion... so the study, and the savings, are flawed."
What's "flawed" is the GOP logic in this case, as it is with most Republican objections to Medicaid expansion: As a Kaiser spokesperson points out, Texas rejecting Medicaid has no impact on the savings Maine would realize by accepting it. But if Maine Republicans are under the impression, at least, that obstructing implementation of Obamacare will increase the cost of health care (which, despite missing the mark in this instance, is true overall), then why are Maine Republicans obstructing implementation of Obamacare?
