@Mau-
I think we have differing perceptions of politicians to say the least. In saying that, I find myself critical of certain actions they perform at various times. Although like you, I would not profess to have a great deal of knowledge about what is going on. I do not however agree this means you should not discuss such issues. After all as Plato asserted
It is just awaiting your entry so I can spring the trap. :)

Edit:
@BoytToy-
New Zealand has what is called a Mixed Member Proportional electoral system. In a nut shell this means that come election day we have two votes to give. One is for our electorate, where we vote for the politician we wish to represent our area. The second vote is for our preferred political party. The party vote is the more important vote as it determines how many seats in parliament the party gets. There are roughly 120 seats in parliament, so if a political party gets 10% of the party votes you can expect them to get 12 seats. Whichever party enjoys confidence of the house is able to form the government. For this they simply need 50% of the seats +1 supporting them. So in a parliament of 120 seats, this means they need support from 61 seats.

At the moment we have seven political parties in parliament (ACT, Greens, Labour, The Maori party, National, Progressive, and United Future). Of these parties, National is in governing through the support of ACT, The Maori party and United Future.

We will however be having a referendum in 2011 to determine if we will keep our current electoral system or change to another. Now while the system New Zealand operates on clearly has its flaws, it is a system I am by and large impressed with. I would like to give it some modifications (such as an alteration to how electorate votes are run). Oh and slightly related, New Zealand was ranked last year as being the country with the lowest level of corruption in government!
