Following is my analysis, not necessarily my stance, so save your fire.
Americans will not blame minors for the sins of their parents, bottom line. So, congress will have to act and some compromise reached between all concerned so that these people who, through no fault of their own – some not even Spanish speakers, are trapped in the middle of immigration law.
Secondly, Americans will blame – and quite rightfully – congress, both parties, including the bureaucratic state ("the swamp"). It was they that, by their fecklessness in failing to act in a timely manner and in Americans best interests, kicked the can along for a minimum 30-years.
Congress bears nearly the entire blame; people who vote mindlessly for their congressman and senator share the remainder.
