As the U.S. once again finds itself between two widely unpopular choices, it is worth reflecting on this 2016 hypothetical from the Economist, a British newspaper: parties centered on narrower but more representative ideas.
America’s presidential system, along with its winner-take-all elections and Electoral College, tends to lead to gridlock and polarization. These mechanisms and institutions were devised before political parties were a thing—or at least as rigid as they are now—and thus never seriously took them into account. Hence, we are stuck with two big parties that are far from representative of the complex spectrum of policies and ideologies.
Rather than the proportional representation you see above, members of Congress are elected in single-member districts according to the “first-past-the-post” (FPTP) principle, meaning that the candidate with the plurality of votes—i.e. not even the majority—wins the congressional seat. The losing party or parties, and by extension their voters, get no representation at all. This tends to produce a small number of major parties, in what’s known in political science as Duverger’s Law.
With the Electoral College, there is a similar dynamic at play: a presidential candidate needs no more than half the vote plus one to win the entire state and its electors. Some states are considering making it proportional, but only Maine and Nebraska have already done so.
This is why you see so many seemingly contradictory interests lumped into one or the other party. In other systems, you may have a party centered on labor rights, another on the environment, yet another for “conventional” left-wing or right-wing platforms, etc. The fragmentation might be messy, but it also forces parties to either appeal to a larger group of voters (so they can have a majority) or form coalitions with other parties to shore up their legislative votes (which gives a voice to smaller parties and their supporters).
Note that this is a huge oversimplification, as literally whole books have been written about all the reasons we are stuck with a two-party system most do not like. And of course, a parliament would not fix all our political problems, which go as deep as our culture and society.
But I personally think we may be better off with a parliamentary-style multiparty system—uncoincidentally the most common in the world, especially among established democracies—than what we have now.
