From what I have read, there are many myths surrounding proportional system. Even in Europe, in the countries that have the system, public interest is dropping off. In political economy, we wonder why people vote because, statistically speaking, the chance of being able to change something is infinitesimally small. People rationalize it all by saying that it will be a catastrophe if they don't vote. In other words, people rationalize about going to vote.
I think a better way of generating interest in the right to vote is through education. In northern Europe, they have achieved high rates of voter turnout. People visit schools to tell young people how the system works. It starts at all levels, municipally, provincially, and at the other levels.
