5. A multiparty system is more stable than a two-party system.
That might sound counterintuitive – won’t PR lead to the two big parties breaking up, new ones forming, shifting alliances, massive political instability and unpredictability?
Yes, in the short term. But consider: Each political grouping has a limited “target market,” a limited number of voters who sympathize with it and might be persuaded to support it. After a few years under PR, each party will have achieved total “market saturation,” recruited pretty much all of its potential support base. And after that point, there will be no more “electoral revolutions” --change will be slow and incremental. Elections will be a matter of a given party gaining or losing just a few percentage points of support. In each party, there will be a solid core of committed supporters, and a fringe of not-so-commited supporters who might go one way or another – e.g., if there is a large Libertarian Party, distinct from a purely business-oriented Republican Party, then there will be a few “swing voters” between them who might, in any given election, go Libertarian or Republican – but never, ever, Green or Socialist. Likewise there might be a set of “swing voters” disputed between the America First Party and the Constitution Party. How those swing voters go will determine shifts in political power – but since they are distributed all over the map in small disparate groups, and none has voting strength out of proportion to its numbers, sudden coordinated shifts in support are very unlikely. No more electoral revolutions, only gradual incremental changes – possibly even on a generational time-scale, no faster.
By contrast, in our present system the only “swing voters” are those hovering about the country’s ideological center-of-gravity. And they do have influence far out of proportion to their numbers, for reasons explained in the OP – which leads to instability. In 1994 we had an electoral “revolution,” putting Republicans in control of both houses of Congress --even though the aggregate national Republican vote exceeded the Democratic vote by less than one-half of one percent (and depending on how the votes were geographically distributed, that exact same vote total might as easily have yielded the opposite result). That makes the balance of power unstable and unpredictable.
6. From the voter’s point of view, a multiparty system is more coherent than a two-party system.
By “coherent,” I mean that it is clear what each party label means and what you’re supporting when you vote for that party. That’s not what we’ve got now. Each of our parties is a “big tent” of several very different factions. Voters often rely on a party label to guide them if they don’t have time to learn details about the actual candidates.
But when you vote the straight Republican ticket, how do you know what you’re really endorsing? A given Republican candidate might be a big-business conservative, a religious conservative, a foreign-policy neocon, or a moderate. A political party that includes George Bush, John McCain, Sarah Palin, Mitt Romney and Mike Huckabee just does not make any sense.
A given Democrat might be a pro-business DLC Democrat, or an environmentalist, or a social conservative, or a black activist, or a labor unionite, or even a socialist. A political party that includes Joe Lieberman, Hillary Clinton, Richard Gephardt, Al Sharpton and Dennis Kucinich just does not make any sense.
Even worse, both big parties lack internal discipline – there is no way to define membership. Candidates and officeholders are essentially independent entrepeneurs, who are expected to manage and finance their own campaigns with no help from the party organization – and whose party labels might be a matter of momentary convenience. If you’re registered to vote Republican you can call yourself a Republican, and even that probably is not strictly necessary. I’m sure the RNC would love to expel David Duke from the party, and the DNC would like to be able to say Lyndon LaRouche is no Democrat – but they can’t. Unlike the more tightly organized parties of Europe, the Republicrats have no membership cards, membership dues, or expulsion mechanisms.
If we have a larger number of smaller parties, each party will also be more ideologically homogeneous and consistent, and the party labels will really mean something unambiguous. It is also likely that these parties would be better organized, better disciplined, and more directly involved in their candidates’ campaigns. All in all, much more coherent.
7. A multiparty system is more entertaining than a two-party system.
This should be obvious – wouldn’t people pay more attention to politics if more different points of view were in play? Even, if there were a few more charismatic extremists in it? I’m sure most of you would shudder at the thought of David Duke or Louis Farrakhan getting seats in Congress – but if they did, wouldn’t that be a fascinating spectacle? Imagine Duke and Farrakhan standing up on the House floor to debate each other head-to-head! Wouldn’t people watch it like they watch a car wreck or a dogfight or a Faces of Death video?
The entertainment value of politics is not trivial. It gets people interested, and a healthy democracy needs that. It also adds more richness and color to our national culture and history. Man, look at how much mileage American comedians and columnists and commentators and pundits have gotten out of one lousy Oval Office blowjob!
On a more serious note . . . remember “Point-Counterpoint,” the segment of 60 Minutes back in the '70s, when Shana Alexander and Jack Kilpatrick would comment on some issue, from a liberal and conservative POV respectively? Imagine how that would have gone if we had a multi-party system and the segment, to be comprehensive, had had eight or nine commentators instead of just two. It would have had to be a much longer segment, maybe as long as one of the news-coverage segments – but so much, much more interesting to watch! So much more intellectually stimulating! Might even be material for a whole separate show! You don’t get anything like that, on for instance, Crossfire – when’s the last time you saw a Green or a Communist get on a show like that?
Heck, people might actually start watching C-Span!
8. A multiparty system can provide a healthy safety valve for nastiness and ugliness.
I asserted above that each party in a multiparty system could play a constructive role. I must admit I have reservations on that point. For instance, in my view the members of a religious conservative party like the Constitution Party are fundamentally wrong about practically everything that matters to them and have nothing whatsoever of value to contribute to the political process. But I see no other reason to exclude them: The CP’s supporters, and those with similar views who are working within the Republican Party at present, are people, they are American citizens, and they have as much right as anybody else to have their views and values represented in the legislatures.
Then there are . . . others. Hate groups. The Southern Party, the Southern Independence Party, the Knights Party (political arm of the Klan), the American Nazi Party. The right-wing militia groups that produced Timothy McVeigh. The “common-law courts” movement of idiots who think they can individually secede from American society. The “Christian Identity” churches who believe nonwhites are soulless animals and Jews are literally descendants of Satan. Also, black nationalist groups – whose views often look just like white racism stood on its head. Do we want to run the risk that if we changed our electoral systems, these people would pool their votes and actually get a couple of members elected to Congress, or to some state legislatures? In Britain, where PR is an actual issue right now, some people oppose it because they don’t want to risk the racist National Party winning any seats in Parliament.
Now, it is possible to construct a PR system in such a way that very small parties can’t get into government at all. In Germany, a party needs at least 5% voter support to get into parliament; this bar has frozen out neo-Nazi organizations while sometimes letting in the Greens, sometimes keeping them out.
But suppose it happens anyway?
My answer is, it wouldn’t necessarily be all that bad, and it might serve a useful function. The idea of my tax dollars going to pay for the salary and staff of Congressman David Duke does make my gorge rise. But he’s only one vote. I don’t believe pure-d racial hatred has broad enough support in America any more to support a very large political party. There’s still a lot of racism, yes – but it’s one thing to unthinkingly accept ethnic stereotypes or to feel a certain esthetic or social distate for certain ethnic groups; it’s quite another thing to base your entire world-view and politics on ideas of racial identity, and I believe the latter way of thinking is extremely rare in today’s America.
Furthermore, the chances of such a party producing an American Hitler are nil – for several reasons, one of which is that fascism is all about an all-powerful, centralized, national state; but, for historical reasons, the sectors of American society that are the most racist are also the most decentralist and the most hostile to strong national government. Also, if white supremacists can get into Congress, black separatists might also get in – David Duke and Louis Farrakhan will balance each other out, and watching them debate each other will be some real hoo-boy fun! (See point no. 7.)
Most importantly, David Duke in Congress might provide something genuinely useful: A safety valve for the political expression of certain feelings that, unfortunately, do live in many Americans who feel muzzled and voiceless in our current political environment. We have reached a point where nobody who hopes to have a political career will dare to express racist views openly – remember what happened to Trent Lott when he obliquely praised the views of Strom Thurmond? My thinking is, if Timothy McVeigh had been able to look to Congress and see David Duke, or somebody like him, spouting his message of racial hatred and fear at public expense, then maybe, just maybe, he might not have felt so frustrated that he had to make a political statement through mass murder.
I think it’s healthier in general to create an environment where people who hold racist or otherwide extreme views can air them openly rather than festering in silence. Sometimes the best way to treat an abscess is to lance it and let the pus out and expose the infected flesh to light and air.

9. A multiparty system produces more coherent and meaningful messages than a two-party system.
Campaign rhetoric nowadays tends to be, well, vague. Sometimes you can hear a politician give a speech beginning to end without learning anything about his or her politics. Political ads are as imagistic and meaningless as the consultants can make them. I think one reason for all this is that, in a two-party system, a politician can succeed only by winning support of a voting majority. If you want to get elected to Congress, you don’t dare say anything which might alienate 50%+1 of the voters in your district, even if it’s something you think urgently needs to be said. You make your messages innocuous and ambiguous enough to have appeal to as broad a swath of the electorate as possible, and always make the swing voters in the middle your principal target zone.
In a multiparty system-- based, let us say, on the multi-member-district form of PR, which each district electing a ten-member delegation – you don’t need a majority’s support to win – only a substantial minority. This frees you up to say what you really think. If you’re a Green in your sentiments you can campaign as a Green and talk the Green line. Same if you’re a Libertarian, etc. It doesn’t matter who else you make made, just as long as you can win the votes of the necessary 10% of the voters.
As a voter, wouldn’t you rather listen to campaign ads and speeches that really say something? Even if a lot of them make your blood boil?
