Arbitrary decisions, in which the outcome is mostly at the whim of the official (elected or otherwise) are the primary ingredient in political power. The capacity for power politics is inversely related to the general arbitrariness of decision making.

Downside: Arbitrary power fuels patronage and enables decisions that are contrary to the public interest.
