Why do you assume that it does not now actually matter?
Because the election is over.
Let’s pretend for a minute that somehow its proven he’s ineligable, say hello to President Biden or would it be Pelosi. Since she’d be next in line and Biden would be ineligible being on an ineligible ticket.
I also think it would strike people as sore loserism to be bringing this up now and not back in 2007 when, like I said before it could matter.
