One of the best known “anchor babies” is Rafael Edward Cruz, who is better known as Ted Cruz.
It is commonly believed that Ted automatically became an American citizen upon his birth on December 22, 1970 because his mother was born in Delaware, but the truth is actually a lot more complicated than that.
Cruz's’s mother, the former Elizabeth Darragh Wilson was apparently born in Wilmington, Delaware. So far, that means that any child that she gave birth to would automatically become an American citizen, regardless of where that child was born.
Ted’s father, Rafael Bienvenido Cruz was born in Cuba. In 1957, he left Cuba to attend college at the University of Texas in Austin by virtue of a student visa. The only money that he had at the time was $100, which he had sewn into his underwear.
He was able to obtain an exit visa from Cuba due to the fact that the family attorney bribed a Batista official to issue the visa. Due to the regime change in Cuba in 1959, he was granted political asylum in the United States following his graduation from college in 1961.
By 1970, he had remarried, and moved to Canada with his second wife, Elizabeth Darragh Wilaon. Together, they owned a seismic-data processing processing firm for oil dealers.
At some point before their son “Ted” was born, they both became Canadian citizens. As a result of the change in his nationality, the elder Cruz lost the student visa that had been issued by the United States. Although Canada DOES allow dual citizenship (as does the United States and 43 other countries) the privilege did not exist until February 15, 1977. As a result, Ted’s mother was a citizen ONLY of Canada when he was born - and so was her newborn son.

The family later moved back to Texas, where Ted attended high school.
The status of United States citizens is very broad, and reads as follow:
A person born outside the geographical limits of the United States and its outlying possessions of parents one of whom is an alien, and the other a citizen of the United States who, prior to the birth of such person, was physically present in the United States or its outlying possessions for a period or periods totaling not less than five years, at least two of which were after attaining the age of fourteen years.
Due to the fact that Elizabth Darragh Wilson had lived in the United States for at least 5 years before moving to Canada, her children technically would be America citizens. However, since Canada did not allow dual citizenship in 1970, neither she or her son would have been allowed to be citizens of both Canada and the United States.
In order to be a United States senator, an individual must have been a United States citizen for at least 9 years:
Article I, Section 3 of the Constitution sets three qualifications for senators: 1) they must be at least 30 years old, 2) they must have been citizens of the United States for at least the past 9 years, and 3) they must be inhabitants of the states they seek to represent at the time of their election.
Unless Ted himself became a citizen after moving to Texas, he is ineligible for the office of United States senator, even though he was elected to that office in 2012, a mere 7 years after his father finally got around to become a citizen of the United States. Since he renounced his Canadian citizenship is August of 2013, he technically isn't a citizen of ANY country.
The requirements to be a United States President pretty clear cut:
No person except a natural born citizen, or a citizen of the United States, at the time of the adoption of this Constitution, shall be eligible to the office of President; neither shall any person be eligible to that office who shall not have attained to the age of thirty-five years, and been fourteen years a resident within the United States.
None of us believe that Ted Cruz is fit to be President, but the circumstances regarding his birth actually mean that he does not meet the criteria to be elected either to his current position, or the office of the Presidency.
