What's a BLM case? Do you have an example?

If the judge has a one degree of separation personal relationship with the party, then yes, they should.

If the relationship is demonstrated to be as close as the Jones-Trump-Judge in this one, sure.

Recusal is evaluated case-by-case so an all-for-everything situation, like you've described, is unwarranted.

Indeed - is there a history of democrat-nominated judges acting in corrupt manner enriching the politicians that nominated them? We're not comparing apples to apples here. One team is playing by the rules, and one team has burned the rule book, eaten the ashes, then shit out the ashes, then ate the shit again.
