How could Kobach still believe he is correct?

How could Kansas Secretary of State Kris Kobach think that Kansas’ law requiring proof of citizenship to register to vote is constitutional when a nearly identical Arizona law was tossed out by the U.S. Supreme Court? Kansas City Star contributor Steve Rose suggested several reasons, including: “His ego is so bloated Kobach cannot conceive that he could possibly be wrong,” “Kobach is so anti-immigrant (OK, illegal immigrant) he is blinded by his own prejudices,” and “Kobach is so unbelievably ambitious that he will step on anyone and stoop to any level to raise his own profile.”
