In various times and regions, Jews have belonged to conservative parties like the UK tories or French Gaullist parties, for instance. But they are virtually absent from rightist politics. The reason is clear enough. Anti-semitism is almost inevitably and almost always part of rightist political movements. It is a natural feature. This is not always explicitly so. It is not always that way at first, but eventually it is always there.The right hearkens back to, and attempts to resurrect, a past that never existed, and this past is largely Judenrein.
Jews, and most other minorities, do not exist as human beings with agency in this idealized vision of the past.
They are either absent, or meek stereotypes.
