Anne Applebaum has published in Atlantic this chilling piece about the Polish move away from democracy. The underlying thesis: some, many perhaps, in Poland think the country is better off if it "is ruled by people who deserve to rule." The fundamental claim for democracy is that all citizens collectively should decide by a majority vote, or at least a healthy plurality, who "deserves to rule." Step one down the dismal Polish slide toward authoritarian illiberal autocracy is for citizens not to vote. The easiest way to convince people not to vote is to adopt a system in which their votes don't matter. So, to make a big story really short, Poland and the United States need to make sure that every citizen's vote really matters -- matters to the decision about who rules, matters so much that the candidates for president want and need to win most votes, matters in determining the winner, matters as much as everyone else's vote (because unequal voting power means someone's vote doesn't matter as much, and maybe doesn't matter at all).
The United States should make sure that all votes for president matter in all these senses, and the winner of the presidential election should commit to persuading Poland and every other country of the world that following the example of this reform will make every country better off.
