How can we challenge the Two Party System of Politics?
This question is a hot dialogue topic in the Wisdom Project. Several strong solutions have been discussed. I will add a new page to Wikiwisdom for each solution I find strongest.

First up: Proportional Representation

Quote from Wiki Wisdom:

Suppose a state has 10 seats in the house of representatives. Rather than having 10 separate elections in 10 separate sections of the state, have one election for all 10 seats, and have the seats given out to candidates in proportion to the number of votes they received. If 10 percent of the population votes for a third party candidate, then that candidate will have won a seat in congress. The typical results from such an election might be 4 Republican, 4 Democrats, 1 Green Party, and 1 Libertarian candidate win seats in the House of Representatives. Every political group in the state with at least 10% of the population's support, could gain a vote in congress...
This type of system would ensure the validity and power of the minority voices in the country. It would legitimize alternative viewpoints and breath a breath of fresh air into our current political process.
