Welll . . . if there’s no standing, usually a judge won’t allow anything to go forward. You can’t fix standing and you can’t “be a little pregnant.”
I’m not saying a judge couldn’t find some reason to allow some action, but I doubt it.
The plaintiffs have to find some othe way to reach the factual issues, besides the question of whether Obama is qualified under the Constitution to be President. I haven’t followed this at all, so no idea what those ways might be.
Sometimes from what I've read the discovery evidence can actually be useful in the determination to move forward or not though having a lack of standing might mean discovery isn't relevant to the case. We'll just have to wait and see, hopefully he rules tomorrow.
