Pick any one:
1 His relationship with the prosecuting Attorneys firm that is a heavy Democrat Donor and hired Hillary for hundreds of Thousands to speak at their firm.
2. His Being a senior Board member of a group giving out Scholarships to Illegals,
3. His Rulings where he refused to dismiss a case with no Plaintiff because she withdrew,
4. His Membership in a La Raza Lawyers Group that links to and co-mingles with the the La Raza Councel including cross linking their web sites and shared community projects.
5. He on his own initiative without it being before him advised the Plaintiffs attorneys to add RICO charges.
Any one triggers Canon 2.
The more people learn of this, and the Media is ineffective at keeping this suppressed, the worse the back lash will be and the better for Trump it will be.
Let's pay closer attention to your talking points.
1. If this Judge having an association with a Hillary donor brings his ability to be an impartial judge under suspicion, why then does the fact that Donald Trump (and his son) were direct donors to not only Hillary Clinton's Senatorial campaign, but Harry Reid's and Nancy Pelosi's. He also donated $100K to the immensely corrupt Clinton Foundation and $50K to Rahm Emmanuel's campaign.
Why do those actions not disqualify Trump from running as the GOP candidate?
2. The Judge is a Senior member of a group that gives out scholarships to Hispanic students, not to illegal aliens. The fact that some of those students may be illegal aliens is irrelevant, since California law allows for illegal aliens to attend college, and it is not the Judge's responsibility to enforce Federal immigration laws.
3. If someone has an issue with that, the issue wuld have been brought forward.
4. He belongs to an ethnic legal society, much like the IABANY (Irish American Bar Association of New York) or the AAJLA (American Association of Jewish Lawyers and Jurists). Nothing to do with the extremist La Raza., except that perhaps the exist in the same Universe.
5. Judge Curiel did nothing wrong.
