Yes all presidents are guilty for allowing the border to be left wide open but NONE of them ever rang the amnesty bell like obama. The collapse of the southern border is now on obama’s shoulders this is his administration his responsibility. He lied to the country when he said the border fence was basically complete http://savingtherepublic.com/blog/2014/07/obama-napolitano-carney-lied-us-border-secure/ . He stood at the podium in the Rose Garden more or less telling illegals to come misrepresenting DACA. He is one telling DHS to back off deportation policies and he is the one who has yet to give a speech directed to the world that the US border is closed. His silence is an indictment that he wants the border left wide open with the help of our elected leaders not enforcing the laws on the books!
Yes big business and their pals in the US Chamber of Commerce is guilty too but again they get away with it because govt refuses to enforce the laws on the books. Govt is the problem with illegal immigration because they choose not to do anything. In a nutshell they want their big donors and new pool of voters!
