The greatest service Marco could perform for his country would be to announce: “Although I have been asked to consider running for the Presidency of the United States, I must notify the electorate that, because I was not born of two American citizens, I am not Constitutionally eligible for the office of President.”
So far, Rubio has not seen fit to do this—either because his parents WERE both citizens at the time of his birth, or because he does not have the imagination or courage.
The reason I call this a “service” is that, were Rubio to make this announcement BEFORE the election of 2012, everyone would be able to reach the logical conclusion regarding Soetoro’s eligibility, since it is an unquestioned fact that Obama’s father was a foreigner.
Or because he realizes your definition is wrong, and since he was born in the US, he is in fact a natural born citizen.
I think Rubio is very promising with good values. If he continues the same way, I'd like to see him run eventually for president.
Most likely it's because he's not buying into this birther b.s.
