Social Security was passed under Democrat FDR with a Democratic Congress. Likewise Medicare was part of Jojnson's Great Society, passed with the help of a Democratic House and Senate. The Obama campaign tried to woo the elderly and upper middle age voters by painting Romney and Ryan and people that would take their Medicare benefits away from them. It didn't work. Even with Ryan's Medicare reform plan and Romney running on a platform to reform (change) Medicare and Obama promising seniors that he would keep Medicsre the same, Romney still won seniors handily.
