The stupidity that Donald Trump has displayed during his campaign may only be the tip of the iceberg. There are not enough white men in this country to elect Trump this fall. He needs the votes of more women, blacks, Hispanics, and other demographics. So, what does Trump do? He brands the judge presiding over one of the Trump University fraud cases a "Mexican." The judge has a Spanish surname but was born in Indiana and is a Mexican citizen.

This comes on the heels of insulting female Hispanic New Mexico Governor Susana Martinez a day or two before asking for her endorsement.

Trump also recently used the phrase "Where is my African-American?" at one of his recent rallies.

Trump Presses Case That 'Mexican' Judge Curiel Is Biased Against Him

Donald Trump is intensifying his attacks on the federal judge presiding over fraud lawsuits against Trump University. On Friday the presumptive Republican presidential nominee, dismissing criticism from legal experts on the right and left, pressed his case against U.S. District Judge Gonzalo Curiel, saying the Indiana-born judge is biased against him because "he's a Mexican. We're building a wall between here and Mexico."

Trump made the remarks, and others like it, repeatedly, in interviews with CNN and The Wall Street Journal, referring to Judge Curiel variously as "of Mexican heritage" or just "Mexican." But the message was always the same, that the judge had what Trump called "a conflict" because of his ethnicity.

At a rally in San Diego last week, Trump characterized the judge as "a hater of Donald Trump, a hater. He's a hater." And "they ought to look into Judge Curiel."

In public, Trump has called repeatedly for the judge to recuse himself, but his lawyers in fact have not made any such request.

That is undoubtedly because court precedents are unanimous in holding that race, ethnicity, gender, religion and sexual orientation are not themselves grounds for disqualifying a judge. If they were, legal ethicists observe, the legal system would fall into chaos because no judge would be free from taint. The five Supreme Court justices who are Catholic could not rule on a case in which the Catholic church participated, but neither could the other justices who are not Catholic.

Moreover, while Trump is free to say anything he wants about the judge, the lawyers in the case are bound by the professional rules of conduct and could be sanctioned for making such charges about Curiel without actual evidence of bias.
