PR systems have been well discussed as an alternative to Westminster version of democracy (where Canada and the USA belong), including on Medium. A Medium contributor called Fred-Rik was writing good articles for PR.

For sure, PR voters need not consider strategic factors when casting their vote, ensuring that their vote doesn't go to a party that has no chance of winning a FPTP contest. And a PR legislature is better at representing the will of the people than an FPTP legislature.

But the are still many political machinations within PR. Inside all political parties is an insidious contest for more status, influence, and power, for which PR has not been able to eliminate:

This contest is clouding the judgement of our elected representatives. And PR systems are not impervious to dysfunction and corruption. Israel is a good example today.

On another note, British Columbia has tried three times in 16 years to address the political imbalance that their FPTP elections cause. All three times, the citizens rejected the change. Mr. Trudeau tried to move Canada towards a PR system, but too much public pressure formed:

There is a lot of talk about of implementing a RCV in the USA, and individual states have the right to make this positive change. So it is doable, but we are probably looking at 30-year time period. And the USA will still be governed by political parties. Public policy will still be clouded by who sits in which chairs.

If 1% of Americans start working on the TDG, it can be built in 20 years. Why not go for a better system in a shorter time.
