Silly question, I think, but can individuals add their names to the Republican lawsuit?
Check out Lin Woods Twitter. He’s attempting to be placed on the law suit as an individual but has yet to be docketed.
I'm not a lawyer, but bill them by the hour. I'm not certain if a private individual might join the case, but do keep in mind, at least part of the rational of this being filed by Texas is that Constitutionally, disputes between the states go directly to the SCOTUS, so there are no lower district or appellate court filings, appeals, etc. A case between states goes directly to SCOTUS. No individual enjoys this privilege, although I would think that would not necessarily exclude and individual from joining (especially provided they were not a citizen of one of the states that has already joined).
