Jackson was from Tennessee, not born there. That’s where the reference to “west of the Appalachians” comes from.
There has long been a dispute between North and South Carolina (even debated in Congress in 1929) over where Jackson was born.
I don’t know if Eckert is correct or not in his assertion that Jackson was born at sea.
My point was that the “controversy” over where Jackson was born could “potentially” be used to establish a precedent that even though questions exist about where he was actually born, Jackson did ultimately hold the office of President.
But, yes, Jackson was a citizen when the Constitution was adopted and was therefore eligible for the presidency. I’m not sure why the author claims otherwise.
True, but your post says he was born west of the Appalachians. He wasn't.
