I don't think anything will move the Trump True Believers until they become convinced that they are supporting a loser and I can't think of ANYBODY who is more worthy of that title than Trump. The problem is that its kindofa secret. Everybody knows about some of his failures but nobody talks about all of those that are known about from his handling of the 450 billion dollar present (result was bankruptcy) from daddy and onward.

Once everybody understands just how much of a loser Trump is I suspect at least some of those currently bamboozled might change their minds.
