>>>>CPI,CPI-M & CPI-ML are 3 distinct political groups(I get the feeling you are confused on that).
You are right. I could be confused on this specific group. But I've seen many congressional records, historical documents, and FBI reports that show these groups aren’t separate independent organizations, but are actual auxiliaries and/or divisions of each other.
Thank you Calpernia, this article left me confused - every time I read it.
