Article II of the Constitution, which addresses the powers and duties of the President, makes no mention of executive orders at all.  The Second Amendment of the Constitution establishes the absolute right of Americans to keep and bear arms, and that this right shall not be infringed upon by the federal government. There has been talk of requiring registration of firearms and requiring some type of identification to purchase ammunition.  History has shown that mandatory gun registration could lead to gun confiscation.  In addition, if ammunition purchases are monitored, records could be used to ascertain what kinds of firearms a citizen possesses and how much ammunition they might be using.  Also, limitations could be placed on how much ammunition could be permitted to be purchased within a certain time frame.  I would hope that President Obama would not be so bold as to issue an executive order intended to deny or diminish any of our constitutional rights.  All of our elected officials have taken an oath to protect and defend the Constitution.  We must hold them to this oath.
