The birth fact patterns are not the same. Obama had one citizen parent (mother) and claims to have born on US soil. Just being born on US soil is enough to confer citizenship at birth, regardless of the citizenship of the parents.
Cruz had one citizen parent (also mother) but was not born in the US. His claim to natural born citizen status stands on a different foundation from "born on US soil."
Just saying that a rule can be formulated that includes one, but not the other. Not saying that the rule does so, just saying that the two cases aren't similar so that if one makes it, the other automatically does. Cruz's claim is based on having one citizen parent, and that being sufficient, without more.
There is absolutely nothing that substantiates the claims that zero's father was the kenyan student or that his mother was Stanley Ann Dunham. You do not know who his mother and father were, you do not know when he was born, you do not know where he was born. And until you do know, any discussion about his citizenship status would appear to me totally meaningless. IMO.
Obama has never proven he was born on US soil.
That Birth Certificate he produced is as phony, as they come.
His Social Security card is phony and did he ever reapply for citizenship when he left Indonesia.
I realize this is all Birther stuff, but the fact is he has never disapproved any of it.
