How does the Revolution affect the individuals of Animal Farm both the leaders and followers?

On one level, the revolution causes great change.  The
humans are no longer in power on the farm.  The animals are able to carry out Old
Major's dream of a social and political order where animalism is present.  To a great
extent, this is something that impacts and influences all forms of life and all aspects
of consciousness on the farm.  Yet, the flip side to this equation is that while the
animals are able to possess political control, there is little real change.  Animals
have replaced humans, and this is something that Orwell brings out to a great extent. 
The abuse of political power and desire to consolidate control over the animals are
realities that still affect those in the position of power, regardless of animal or
human.  One of Orwell's critical points being made is that there is an intrinsic
condition to political power in the modern setting that is predicated upon control. 
This is something that has to be checked and scrutinized at every turn and Orwell brings
this out in his depiction of how the revolution affected both the leaders and followers
of life on the farm.
