If there was any question whether the immigration debate is still raging in the heartland, it was probably settled the moment that Kansas Secretary of State Kris Kobach demanded the birth certificate of a 90-year-old World War II pilot. On a stiflingly humid September day in central Kansas, Kobach pushed through the courtroom door, head bowed, a storm cloud on his face. His ever-present red tie, front-swept hair and 2-inch sideburns framed an even jawline. He is a secretary of state here, a man who has authored some of the most stringent immigration legislation in the country — often traveling the nation to argue his own cases — and has cleared a viable path to the governor’s mansion. Behind a lectern facing the judge, an ACLU attorney finished her initial fusillade of oral arguments with a comment directed at Kobach. “He has to use such convoluted reasoning,” said Sophia Lin Larkin, representing a class of voters who the ACLU argued was being treated as second-class citizens in Kobach’s voting system. “This is simply another variation of his mistaken understanding in this case.” Kobach’s understanding of the voting-rights case is an extension of his philosophy on rights accorded to any American: They are conditional offers that only apply to those who can prove their citizenship.
