Previously the Congress would legislate, ie determine what the laws of the United States will be and, assuming that they did not violate the Constitution, set them up to be executed by the executive branch, ie the Presidency and his designees.
Now, Presbo sets “policy” to be acted upon by cabinet departments that he has set up and now operates independently of the Congress. So until and unless Congress explicitly prohibits a particular activity(which will never happen under a Senate bottlenecked by Harry Reid), the law is whatever Presbo says it is.
No Dream Act? No Problem. The major portions of the Dream Act are now the operating policy of the Department of Homeland Security, and it will operate as though the law had actually been passed, for as long as and until Congress manages not to be hamstrung by the lib-prog controlled Senate.
The upside, millions of illegal immiigrants will now look favorable on Presbo and may influence voters.
The downside, millions of illegal immigrants will now get permits to legally compete with unemployed Americans for the few available jobs out there, even with the unions. This may not set well with the folks that have been holding on to professing loyalty. Who just got bussed.
