Oh, and just for the record the Democratic National Committee is a PRIVATE organization and is in no more constrained by its “charter” than any non-tax deductible organization is.
Whoever is suing is wasting their money if she or he is paying for lawyers (who are laughing at him or her) or her or his time.
Nobody has “standing” to sue a voluntary organization that does not charge dues for anything except a personal injury or reputational tort.
Really. You could look it up.
