Even Obama himself is hyping this up saying he is going to do something "broad" and "to the full extent of his power", why the heck would he even bother saying all that and not do anything, especially when everyone expects nothing to happen anyway...so why bother hyping up something as sensitive as immigration relief if he was really planning on not doing anything.

This is how I logically see it, but crazier stuff has happened...lol...

The thing to worry about though is where is he going to stop short at, who is he going to exclude from his relief (as there is a strong possibility he may not want to give relief to various groups as to not make it seem "too broad")
