Obama to sign gun control legislation 27th of July

Obama bypassed Congess to halt deportations. He bypassed Congress to provide massive amounts of aid to Palestine. So why is it so hard for some people to believe Obama is capable of restricting gun ownership?
According to Dick Morris, Obama will sign the Arms Treaty on July 27.

 
The purpose of which is, according to Morris:
The real purpose of this is that it will set up an international agency that will be in charge of controlling the flow of arms throughout the world. And while it will theoretically have jurisdiction over arms flows across national borders .. you know like the Interstate Commerce Clause... we see how that can be expanded. And it really will have the authority to tell member nations to adopt policies within their own countries to facilitate regulations of flows across borders. And those could include, will include, registration and may well include bans on arms and guns.
Now if this treaty is ratified by the Senate, it assumes parity with the 2nd Amendment. It is as if there is a new 27th or 28th Amendment to the Constitution. Because the Supremacy Clause of the Constitution says treaties are the law of the land and cannot be overriden by acts of Congress or acts of the state legislatures.
For those of us who value the 2nd Amendment right to bear arms, this is absolutely pivotal .. they changed the venue but it is the same fig
