Lennism in Political Science?

I always suspect if i lined up ten people, id get 15 different answers on what lennism is. What has been the base definition of lenonism as it's used in political science? I think it depends on which branch of political science you are speaking to. And where my kind of origins are. My roots are is in the more institutional side of political science. That's where i think alenanism makes the most senses.
