I think it is also important that it is States that are the plaintiffs. If the plaintiffs were citizens of Texas then the case would be thrown out due to their lack of standing. I would claim that they had standing, but many cases seem to suggest that if a person is not financially harmed by another’s action then they have no standing.
Individual voters have standing but they must start at the lower court and be able to battle uphill against the time deadlines and they must have the legal capital to wage their arguments.
States have ‘original jurisdiction’ so they can start at the very top, the US Supreme Court.
and states have the budget if they commit tot he fight.
The US Supreme Court is going to take a note of significance to a group of States with a sound argument in the context of a historical crisis.
