Politics, Why do we need them?

I am not impressed with the way politics are run nowadays. I'm quite offended (and I know that that is my choice to be offended) that groups and individuals use that fact that the average person is uniformed on political matters and they feed they "pretty" information to sway their opinion. Many topics in politics with regards to financial matters can be cut and dry but it is also dodgey to keep people from knowing the Truth. I'd go in to specifics but this was actually a test blog even though I still think this way.
