Question

how power is divided among political parties

Answer 1

Whether they are conservative or revolutionary, whether they are a union of notables or an organization of the masses, whether they function in a pluralistic democracy or in a monolithic dictatorship, parties have one function in common: they all participate to some extent in the exercise of political power, whether by forming a government or by exercising the function of opposition, a function that is often of crucial importance in the determination of national policy.
