Neoconservative means new conservative and has referred generally to people who were raised in the intellectual, eastern seaboard liberal left environment but saw the problem with leftism, mainly due to an understanding of communism, and moved right in the face of their social group’s near universal belief in leftism.
Understandably, many neocons have been Jewish, not all. Norman Podhoritz may be the grandfather of neoconservatism.
There also is the group of neocons who did not necessarily come from a left, eastern seaboard family and environment and therefore did not convert from left to right, but have been part of the liberal left social structure, lived and operated within it yet held on to conservative values. This is a Ted Cruz neocon as an example who has been through all that the east coast liberal left establishment entails in his Ivy League career.
Trump is a noncon.
