These seem like the top possibles to me:
1) The American Economy will collapse without it.
2) The money interests who need to buy our debt regularily demand it.
3) The business interest who run what’s left of America demand it.
4) It is well known that if we start doing this legally (throw them out like the law says) there will be escalating violence by them? If anything like this is it they _must_ be tossed, soon.
“It is well known that if we start doing this legally...”
This would seem a good start....
