Democracy may be flawed (the USA is a Republic not a direct democracy like the UK) but I prefer a voting system that I can explain to an 8-year-old. A system for voting that is based on a mathematical model that a select few - the people who designed it - can understand seems dangerous.
Democracy and Quadratic Voting

@khurtwilliams The main problem are two-party systems that vote in single-mandate districts by a strict first-past-the-post. This excludes or at least marginalizes many non-mainstream and minority movements and ideas from any influence on how a country is governed and is deeply undemocratic as such. Time for proportional voting and a more diverse political landscape. In the US and in Great Britain.
Interesting. If you are correct, that would explain why Republican and Green Party voters in my state - people like myself - feel like we can't be heard in our Always Blue Democrat state of New Jersey. I may not bother voting in the next US Presidential election. I dislike the Democratic and Republican parties, so my vote is irrelevant to the outcome.
I dislike the current two-party political system, but I do think the answer is fewer political parties; perhaps just one or better yet, none. I think the answer is the legal elimination of political parties. George Washington warned against them.
