Actually, yes, an anchor baby could run for POTUS much as you or I might hate the concept. Cruz was born a US citizen despite the locale of his birth by virtue of his mother's citizenship. That's been clear from the nation's birth. What the Founding Fathers wanted to avoid was someone like Arnold Schwarzenegger or Liam Neeson moving to the country and running for the head office.

Obama's anti-American attitude was due to how and where he was RAISED, not where he was or wasn't born. I have never bought into the birther argument simply because his mother was a citizen so it didn't matter. I think he's used it as a useful distraction and way to poke fun at people who oppose him. What people should have objected to was the fact he was RAISED by anti-American communists. He doesn't understand American culture or heritage because it's something he had to read about rather than live.

BTW, neither Cruz nor McCain are the first to encounter this made-up "issue" and I'll take advice on Constitutional law from Lawrence Tribe when I become an Obamabot.
