It is odd to notice that the English version, at the entry "political party" says something completely different: "A political party is a political organization that seeks to attain and maintain political power within government, usually by participating in electoral campaigns".
Italian constitution
From Wikipedia definitions one could deduce that the task of a political party is to defend the interests of who votes for it.
It shouldn't work like that: a party's task, in my opinion, is to govern the Country.
And to govern, in a democracy (as the etymology of the word itself suggests: government of the people - the whole people, and not only the majority) means to work for everybody's interests, also of who didn't vote for it.
What's the need to vote for one party instead of another, if any winner would anyway do everybody's interest, then?
The answer is that it's not so obvious to decide which are the actions to do on a legislative/executive level to reach that goal. For example one typical interest of all the citizens is to increase the wealth of the State (and so, atleast on average, the wealth of the citizens). This is the goal of both Capitalism and Communism philosophies, but they want to obtain it in completely different ways.
The need to vote is to decide which way that goal should be obtained. Who votes shouldn't do it to promote its own interests, potentially opposite to other people's interests, but to contribute to the achivement of the whole community interests.
Then, there is the problem to define on one side the set of people that have the right of vote, and on another side the set of who is subject of the decisions of who wins the elections. Surprisingly the two sets are not the same.
For example it is obvious that underage people are subject to the laws although they don't have the right of vote. There's also an open discussion in Italy about the right of vote for the non-citizen immigrants, but it is unquestionable that the laws dictate also their rights/duties.
The distinction of the two sets is dangerous, because it shows that there is a set of people that decide how another set of people must behave, while those last people don't have any possibility to give their political point of view. In my examples it is not a problem for underage people because they are the children of who has the right of vote. But in the case of non-EU immigrants for example the thing is different. If the voters vote for their own interests and not for the common one, the immigrants are discriminated. Moreover there is the problem of the looser minorities. Since the majoritiy is the one who governs, in a democracy a vote aimed at the realization of the personal interests of the voters could discriminate not only the non-voters, but also the minoritarian groups of voters. Nazism warried to obtain the interests of who voted for it, also if this included also the extermination of the Jews.
Actually this cannot happen if there is a Constitution that prevent it, but this works only if also political power is submitted to Constitution. If instead the winner political party can change the Constitution, there is an obvious contraddiction.
The sense of this post is that, even if this looks to me obvious and necessary for a real Democracy, it seems that nor the elected people of the majority in Italian Parliament, nor their electors notice that those rules are not respected. And, by the way, not even in the minority.
And to pay the fee is the interest of the Country.
