I want to know more about Abbie Hoffman. I have noticed a small information about him on http://www.babynology.com/famous_namelist.php?gender=&stw=Abbie&origin=american&cat=politicianand google. Can any one elaborate more about him.

Who are those politicians whom we always think of when the politics comes in our mind? I want to know the names of those politicians who left their impact somehow in our mind.
