I think it is very funny how almost every politician ever (in electoral democracies) always disappoints many people.
The only good politicians in the public mind are those who died before they could disappoint, it would seem.
Many times I have wondered why this is the case, and I think a part of the problem lies in voting itself.
Aside from the many people who let their private interest triumph the public interest (media, lobby, politics, business etc.) and screw up the voting procedure, there might be something wrong with the procedure or the way we see it as well. How it is traditionally seen is that somehow the outcome of the voting procedure is a social choice. A choice of law or a person which has a mandate of the entire community. This is the ideal view. However, when looked at realistically it is more of a game. It is a game which tries to replace violent conflict between social groups in a coordinated rivalry. The minority doesn't feel represented by the "social choice". Rather, they grin and bear it because that is what citizenship (sportsmanship in the game) demands of them. Thus, aside from the lots of cheating that happens in this game I think the disappointment partly stems from unrealistic expectations.
What should be a solution then? I think society would benefit from a widened idea of democracy. We automatically equate democracy to voting, but we forget that the Ancient Greeks (which we call our inspiration) picked their rulers by a random lottery. I think the core of democracy lies not in having elections or not (which is a dichotomous category). Rather, I think democracy is the degree to which consultation between citizens, the government and also other political actors (like the Federal Bank) are characterized by broad, equal, protected and mutually binding consultation. This definition is inspired by the historian Charles Tilly, and I think it opens up other possibilities than a simple vote. For example, when it comes to decisions of a smaller scale deliberation might be used as an instrument. This involves selecting several citizens (selected with a stratified sample), informing them on the issue over the course of several days and let them discuss it. After a few days they should reach a decision. Some experimentation with this is already happening. For example, in Porto Allegra in Brazil, some neighborhoods are given a certain budget and the inhabitant can deliberate and decide themselves how this is spended. The results of this experiment are very positive so far, and the social divides actually lessened (even that one of education).
What is the great political divide? Numerous exist, class, religion, education and they all depend on context. However, there are many ways in which these can be bridged and we are allowed to play in the game we call politics.
