Now I understand that some of you have never READ the Constitution, so it's understrandable that you think a governor is supposed to protect the borders. If you are going to post at a site like this you really should at least attempt to read and understand our founding document. It's only about 14 pages long and was written so the average citizen at the time, who were basically uneducated, could understand so there is no reason you shouldn't be able to digest the seperation of powers and the powers delegated to the federal government and to the states.
Its all about context, and if your inability to understand that basic concept is any indicator, then perhaps you you should refrain from lecturing anyone about the Constitution since your own comprehension skills are suspect.
