If born on US soil, a citizen, but you cannot extrapolate he would be eligible as a natural born citizen because the issue must have SCOTUS clarification before the issue can be settled based upon the Founders’ intent with the phrase ‘natural born citizen.’
Someone will have to bring a case, they'll take, then, and persuade them to carve out a third category of citizen. For now, there are only two kinds of citizen: natural born and naturalized. And a kid who is a citizen via the 14th Amendment is clearly not in the second category. It's not looking like it's in the cards this time around.
Actually, it would probably take another amendment, probably aimed at solving the anchor baby problem, which the 14th has caused. If such an amendment were properly written, it could also define citizenship for purposes of presidential eligibility. But then, you'd have to get it passed.
