“I’ve done a lot of historical research on it, and so have a lot of other people, and the best evidence seems to be that what they meant in 1788 was something more than just citizen from birth,” he said. “They actually meant a citizen whose birth was sort of natural, not in a biological sense but in the sense of connection to the land. The idea was, that it was something that Congress couldn’t change, unlike the naturalization process, which Congress has monkeyed around with all the time. I mean, for example, in 1934, the first time it said, you can be a citizen who doesn’t need to get naturalized as long as your mom was an American citizen. And that’s ultimately the basis on which Cruz has to rely. The funny thing is, that the kind of guy Cruz is, he’s always been this way. When he was my student he was this way. He’s always said the Constitution always means the same thing that it meant when it was adopted. That’s why he made this funny joke to Trump, you know, saying, the Constitution didn’t change since last September. Well, he thinks it didn’t change since 1788 when it comes to gays and, you know, women and other things. But when it comes to his own ambition, he’s suddenly becomes what he accuses me of being, and it’s a pretty true accusation, a judicial activist. That’s not the guy he is normally.”
