I believe you are sinning my friend, 11th Commandment correct?
Wrong.
California GOP Chairman Gaylord Parkinson created the 11th commandment in 1966. It served Reagan well, against his GOP primary opponent for Governor, liberal San Francisco Mayor George Christopher. By 1976 Reagan was attacking Pres Ford in the GOP primaries, and right up through the GOP convention.
IOW. The 11th commandment was/is a fallacy. Politics isn't for the faint of heat or the thin skinned. Reagan knew Ford was a weak leader. Too bad Ford didn't have the smarts to drop out and let Reagan run against the peanut farmer. Reagan would have won.
