Furthermore, in the majority of cases, we are only allowed to elect those who are pre-approved by The Red Party or The Blue Party. Both parties have biases. Worse they, like the examples mentioned, tend to leans towards self-serving (the party) and/or serving their own mwmbers (i.e., don't offer the best possible representation). It's like cliques in high school all over again.
What I'd like to see is simple. Add "None of the above" to every race. Let The People fully express themselves. Let them give the parties direct feedback about the products they're marketing. Yes, that's kind of what not voting it. Unfortunately, the fact is, the parties don't recognize that as a possible "Crap products" votes. They can phantom that. NotA would stuff it right in their face.
