Rubio does not have dual citizenship. He is first generation in the USA.
Dual citizenship cannot be legally renounced. It can be socially and politically denounced, however, the legal status is intact.
Cruz is lucky he has a dual citizenship with the USA and not Russia. Currently, if a person has dual citizenship they have to register and pay an annual fee. There are parallels to in history that serve as concern:
Because of differing citizenship laws (click here) in Japan and the United States, Nisei born before 1924 were citizens of both countries, a status referred to as "dual citizenship." Dual citizenship status became part of standard criticisms of Japanese Americans by nativist and anti-Japanese groups. Rising tensions between Japan and the U.S. in the 1930s highlighted the issue and led Japanese Americans to launch efforts to encourage Nisei to renounce their Japanese citizenship. Even after changes in Japanese law ended automatic dual citizenship for Nisei in 1924, anti-Japanese groups used the issue of dual citizenship to justify wartime measures aimed at stripping Nisei of their U.S. citizenship....
The idea of dual citizenship is an issue. It is an issue of loyalty. It causes doubt in the country about dual citizens. We see this today with Birth Tourism. But, once a person is born to dual citizenship there is no removing it. The facts are the facts.
Those scrutinizing US Senator Ted Cruz for his birth rights are irrational and I think it very unfortunate it was ever an issue for him. I would never vote for him, but, it is has nothing to do with his birth rights in two countries.
Article 2, Section 1 of the United States Constitution prevents all except natural born citizens from serving as President of the United States of America. This issue here is whether or not a person is naturalized. Naturalized is a person coming to the USA from another country and then becomes a citizen with full rights. They don't really have full rights. They cannot be President. They can run for President, but, would never be inaugurated. I think that provision in the US Constitution is very wise. It prevents a King or Queen from being a citizen and capturing the 13 colonies all over again.
US Senator Ted Cruz is an American with all the rights and responsibilities there of.
