Countries already having the democratic set-up face the challenge of expansion. Such countries need to ensure that more and more social groups, regions and institutions follow democracy in their functioning. This involves:
Ensuring greater power to local government.
Extension of federal principle to all the units of the federations.
Inclusion of and *** groups etc.
It also means that less and less decision should remain outside the domain of democratic control.
Most countries including India and US face this kind of challenge.
