H/T @SueInRockville for her thorough research on a matter that can greatly change the political landscape, especially for #2 ranked Republican Presidential Candidate, Sen Ted Cruz.
Ted Cruz has never been (thoroughly) vetted when it comes to his own citizenship claims. He must produce all relevant documents, at least a few of the official papers our own President Obama was erroneously accused of lacking. We know for a fact that he was born in Calgary, so there's one minor anomaly worth investigating. Legal Scholars like Lawrence Tribe at Harvard Law School & Mary B. McManamon of the University of Delaware's Widener School of Law agree that Senator Ted Cruz is ineligible to run for the U.S. Presidency. Remember though, voters in the GOP will ignore certain shortcomings that could never be overlooked in a 'Blah' President.
They have been basing those opinions mostly on their interpretations in the U.S. Constitution's Article Two clause of "natural-born" citizen.
Given that Ted Cruz was born in Canada and similar to the US Constitution, any child born in Canada after 1947 was granted full citizenship.. We must look to Canadian Law first.
