Sorry, I don't buy it. The leaders of this organization aren't out there lobbying for the advancement of all people. They are pushing for hispanics to the exclusion of anyone black, white or asian. They are pushing for the "return" of the South West United States to Mexico and openly advocate for the current state of border lawlessness.
Its a racist organization whatever kind of frilly language is used.
It's "The Race" not because of the name (that we're not supposed to parse, according to the bright fellow that chastised me for doing so), but because of their deeds.
All that said and done, I think it's irrelevant. Trump should not have called the Judge's family history into question. It does nothing to enlighten anybody on his relative guilt or innocence, it just inflames people, which is what Trump seems to be all about anyway.
