How should a Buddhist vote?

Looking at the economic turmoil that had been unleashed by a certain leader of a powerful nation, I wondered what factors/guidelines/principles a good Buddhist should consider that are in accordance with the Dharma when voting? While it is true that democracy doesn’t exist during the Buddha’s time, I assume that voting like all the decisions that a Buddhist made in life can be either skillful or unskillful depending on their intentions, emotions and mental state at the point of action leading to consequences and repercussions. So, how would the Dharma advise us in this situation?
