Eleventh Commandment

A phrase used by Ronald Reagan during his 1966 gubernatorial campaign in California, which read: “Thou shalt not speak ill of any fellow Republican.”

It was created by California Republican Party Chairman Gaylord Parkinson to stop liberal California Republicans from labeling Reagan an extremist as they did to Barry Goldwater two years earlier in the 1964 presidential election. The phrase evidently worked as Republicans united to help elect Reagan as governor.
