thank you for the link to Kris W. Kobach Sec of state response to Eric Holder:
In conclusion, the State of kansas stands firmly on the principles laid out in United States Constitution. SB 102 is fully supported by the Second Amendment, the tenth Amendment, and the limited scope of the Interstate Commerce Claus. The Obama Administration has repeatedly violated the US Constitution for the past four-and -half years. That abuse cannot continue. The State of kansas is determined to restore the Constitution and to protect the right of its citizens to keep and gear arms.
Thanks I was waiting for something like that to show up.
