The word democracy is made up of two Greek words, demos and kratos .
Demos means people and kratos means rule. A democracy is therefore a rule by the people; and not a blind rule by their leaders. In any constitutional democracy, the most important political and civil right and responsibility is to vote in elections. If one does not vote, or is not registered to vote, one should not really express public political opinions. One is only an empty vessel when you do that.
In a Constitutional democracy, it is the rule of law principle which give such rights and responsibilities to all citizens or the people; to exercise their democratic right and responsibility to evaluate the system of governance of the day, and then to exercise their vote accordingly, every five years as in our case. The party with a majority based on the first past the post principle gets elected for a new five-year term.
