The rules on political speech were driven through Congress by LBJ.We should rescind those as they have been unequally enforced and are a bad idea.
They have nothing to do with the Constitution.
Several years ago the Rabbi at my synagogue bad-mouthed Republicans. I wrote an angry letter questioning that and asking of I were still welcome at services. I received a mealy-mouthed reply from the congregation president, saying the rabbi “had been counseled” and of course I was still welcome. It is a conservative congregation but the rabbi is a Marxist.
