Before Obamascare, before Healthscare, there was Mediscare:
George H.W. Bush: Described Medicare in 1964 as “socialized medicine.” 
Bob Dole: In 1996, while running for the Presidency, Dole openly bragged that he was one of 12 House members who voted against creating Medicare in 1965.
From Think Progress:
Over the years, Republicans proposed numerous schemes to slash funding or privatize Medicare. Most notably, in 1995, under the leadership of then House Speaker Newt Gingrich (R-GA), Republicans proposed cutting 14% from projected Medicare spending over seven years and forcing millions of elderly recipients into managed health care programs or HMOs.
The cuts were to ensure that Medicare is “going to wither on the vine,” Gingrich explained. Similarly, during the 2008 Presidential campaign, Sen. John McCain (R-AZ) proposed cutting $1.3 trillion from Medicare and Medicaid.
Now, ask yourself this question: Have you seen any sign whatsoever that the Republicans have mellowed in the past six months? Of course not. Watch what they do, not what they say.
