in 2005, boston university law review published 100-page law review article of far more depth and complexity that examines the constitution's use of the phrase nat-born citizen as a qualification for the presidency. the piece was written while ted cruz was still working in texas government. it was written two years before barack obama began to run for president, and three years before the united states senate decided that john mccain's natural-born citizenship was questionable enough to be worthy of a unanimously passed senate resolution in 2008 declaring that the united states senate, at least, regards him as a natural-born citizen, even though he was born outside of the united states. there is no more authoritative legal analysis of the natural-born issue than this boston university law review article written by sarah duggin and mary collins.
