Again, in this case, it's one or the other.
Well, if someone has found the law that compels it legally — I don’t know why they’re waiting so long to get the birth certificate...
But, I don’t believe that anyone has found a law that compels a candidate to show their birth certificate, hence the very simple solution of getting a state to enact a law that *legally requires* a candidate to show his birth certificate or else he cannot be placed on the ballot...
However, I suspect that there are a certain number who would rather “talk about the birth certificate” than get a law like this passed... :-)
