You must be retarded. They are the same interpretation of Marx, but De Leon's came first.
Even Lenin said this:
What we have done in Russia is accept the De Leon interpretation of Marxism, that is what the Bolsheviki adopted in 1917.

#1 it was before Lenin
#2 he died right before WWI completely changed world politics so the relevancy of his policies is debatable
#3 he had a reputation for being an elitist and a massive asshole
Jonathan Wood
No Lenin came first De Leon is just older
