That didn't really make sense. On the one hand, the author complains that proportional elections favor a limited number of parties, which don't always give voters good options to choose from. And on the other hand, the winner usually doesn't get the majority of seats, forcing them to negotiate with other parties instead of governing unilaterally.
Then there the focus on the left vs. the right, which is no longer as relevant as it used to be during the cold war. If you choose a single faction (such as the left, conservatives, or environmentalists), that specific faction is almost always smaller than everyone else combined. When there are multiple major issues instead of a single overarching question, political divisions become more nuanced than simple X vs. not-X.
