As our health spending crisis escalates and our population ages, Medicare is taking the spotlight, and could well become the most important health story of the 2012 election. At stake in this election is the future of Medicare and whether it will remain a social insurance program, with the government providing coverage for all seniors, or become a private insurance system, with agents selling individual coverage to seniors. Perhaps surprisingly, both parties see the Medicare debate as a party asset. Democrats, who have historically defended the program against budget cuts, have always viewed Medicare as a political gift, but this year Republicans do too. Says Paul A. Lindsay, a spokesman for the National Republican Congressional Committee, "If House Democrats want to engage in debate about Medicare, we are happy to remind them about $500 billion in Medicare cuts they made to pay for their government takeover of health care."
