He really is a Jew. That's why he doesn't want Trump galvanizing anymore support. Trump was never really calling the shots. The Jew always pulls the strings behind the scenes.
the innocent explanation for Jared's advice would be he thinks it would be a disadvantage if Trump were to become fringe. we are assuming the Hill reports honestly and isn't trying to sow division among conservatives.
Granted that Kushner received his power thru ethnic and nuclear nepotism, i really think it's just that he personally is a two-faced snake. His own evil motives explain his behavior, not necessarily his race/faith.
Kushner is a global problem!!
Kushner is heir to the richest Jewish family in New York, and good personal friends with Netanyahu.
He's loyal to Israel first and foremost.
It's pretty obvious Kushner's ethnic Jewish identity is the primary motivator for all his actions.
