Proportional Representation Breeds Confusion
This is a way of giving voting minorities some representation. Ultimately, let's say, 51% vote for a majority candidate. A second-choice candidate who got 49% could under some circumstances still be elected.
But in countries where proportional representation, rather than winner-take-all, systems have been tried, like Fourth Republic France or Israel, the result has been to destroy the two-party system and allow both a plethora of political parties and, often, only poorly focused coalition government.
That system ultimately destroyed the Fourth Republic and has impeded Israel from adopting definite policies, possibly compounding Middle Eastern problems.
The founding fathers in America, it is true, did not contemplate the development of political parties. But such parties seem to be inevitable in democracies, and then the question becomes whether the system of voting facilitates a clear decision at election time.
Great Britain, like the U.S., has a winner-take-all system in separate districts which tends to magnify the disparities in results. So, say, the Labor party in Britain may get only 43% of the total vote, the Tories 38% and the Liberals 19%. But that may leave the Labor party with a solid majority of the elected seats in parliament, and the Liberals with very few.
It's said by some theorists that this is unfair to third parties such as the Liberals. But it does have the effect of electing definite majority governments, able to act.
The Times article probably should have put the issue in more context. Then this might not have seemed such a fruitful reform, although Vogel did make it clear she was mainly talking about at-large elections for city councils and so forth, not single contests such as for mayor or district attorney.
The essential thing to realize is that the American system of winner-take-all has worked fairly well for more than two centuries. The only exception is the electoral vote system in presidential elections, which sometimes has produced a winner with fewer popular votes than the loser, as in the 2000 election, when George W. Bush defeated Albert Gore. This, however, is somewhat of a separate issue.
