It was Really Against Medicare.
Media Matters:
"On August 14, the Drudge Report, Rush Limbaugh, and O'Reilly Factor guest host Laura Ingraham featured a recording of Ronald Reagan speaking in 1961 against "socialized medicine" for the American Medical Association's Operation Coffee Cup Campaign against Medicare. Neither Drudge, Limbaugh, nor Ingraham, however, noted that Reagan was speaking out against an early version of Medicare, which has become very popular since it was enacted 44 years ago, or that Reagan's dire predictions of curtailments of freedom were never realized."
