What is it with Republicans and the idea of "47 percent"?

This 1972 ad for another Republican, that one a sitting President, accuses Democrats of intending to create a parasitic class of welfare cheats.

Also notable is the ad's depiction of a white construction worker. We've beefed up since then. In modern visuals, that guy's appearance would signal deprivation, that he was underfed.

H/t TPM.
