Change in the chilean politics! (one thing)

Hi people
I could change the Chilean politics would principally the political party system and fundamentally the binominal system because this system produces discrimination to the people that want participate in a political position as: senator or Member of Parliament, for example. This system prevents that people without political party can access to the political power. This system is where only two parties or coalition compete for the power! This mechanism excludes to the minority or political parties minorities such as: communist party or humanist party, for example.
This change will produce that more people interest for the politics and could participate in an election for political positions
I believe that the system of election could be a system where only wins the majority and not a system of election proportional, for example, because the community of the local areas knows the problem that affect them, and obviously not to the binominal system
Well, I don´t like the political parties, are strange and not represents the thought of the people
See you!
