It's doubtful any legal challenge would be successful on technical grounds involving both standing and the political question doctrine. However, I think Larry Tribe accurately states what either an originalist or one who believes in original intent would say:
In his emails to the Guardian, Tribe discussed Cruz’s own approach to constitutional issues, noting that under “the kind of judge Cruz says he admires and would appoint to the supreme court – an ‘originalist’ who claims to be bound by the historical meaning of the constitution’s terms at the time of their adoption – Cruz wouldn’t be eligible because the legal principles that prevailed in the 1780s and 90s required that someone be born on US soil to be a ‘natural born’ citizen.”
He added: “Even having two US parents wouldn’t suffice for a genuine originalist. And having just an American mother, as Cruz did, would clearly have been insufficient at a time that made patrilineal descent decisive.

Obviously the same argument would apply to a hypothetically born in Kenya Obama.
I should say it is my opinion your characterization is wrong, the issue is unsettled and reasonable minds have taken different positions.
