So, even the FAM admits that the 1790 law DOES seem to imply such a person is eligible for the presidency.
Not exactly. That document says that the statute gave natural born citizenship to foreign-born children of citizens but says that someone being natural born by statute doesn’t necessarily mean they are natural born for Constitutional purposes. It basically says that we need a court decision to have the answer questioned definitively.
I can handle however the court would decide; what is NOT tolerable is for the courts to deliberately leave us in limbo so they can sucker-punch us if Cruz wins the Presidency. We DO need a ruling, and we need it BEFORE the 2016 primary.
