Ted Cruz, born in Calgary
Marco Rubio, born in Miami, FL
Bobby Jindal, born in Baton Rough, LA
Nikki Haley, born in Bamberg, SC
Other than Cruz, all are born in the United States. Nowhere in the Constitution or case law does it say to be a Natural Born Citizen, you have to be non-Hispanic and white. All, with the possible exception of Cruz, are Natural Born Citizens. So, no treason.
And let us suppose, just for one wild instant, that they were not Natural Born Citizens. Cruz and Rubio are senators, Jindal and Haley are governors; none of them have to be Natural Born Citizens. None of them has formally announced a bid for the presidency. And let us suppose that they had made such an announcement; how would that "have ended Obama's usurpation"? Would that make Obama less born in Honolulu? And even if were born in Kenya/Indonesia/anywhere but America, would the announcements from these four Republicans make him say "OK, you've got me, I'll resign now"? Or would it make senior Democrats force "The One," as you say they call him, to quit?
Very racist, very intemperate, and very stupid.
