This persuasion-buying strategy carries the highest potential yield for the party because the payoff can create a social multiplier: The effect of the clientelistic gift can be magnified via the conversion of multiple voters within a payoff recipient's personal networks.

A lively scholarly debate exists around the question of which citizen traits attract the attention of machine
