People often complain about how politicans do not truly represent them. You have to remember how many people these politicians are supposed to represent. Honestly, maybe some of these guys aren’t really representing those that voted them into office, but you’re never going to know for sure. It’s not something you can quantify.
There is nothing wrong with being upset at what politicians do, and there is certainly nothing wrong with voting, but it’s an act of too much self-importance if you expect politicians to do whatever it is that you want. You’re one person!
