Proportional Representation (PR] is generally a good thing, because it eliminates the wild swings in policy that you sometimes get with a 'First-Past-The Post' {FPTP} system. In Britain, where we have FPTP, you can get extreme right-wing governments such as those of the Conservatives under Prime Minister Margaret Thatcher, followed by left-of-centre governments. This leads to a lot of waste. The left-wing governments raise taxes in order to start up programmes designed to benefit the public generally, and then along comes a right-wing government which clears the projects away. Then another left-of-centre government gets elected, and the projects get started once again... So buildings are built, knocked down and built again, staff are hired, fired and hired again. Any kind of PR system will help to avoid this. Another general advantage of PR systems is that they allow you to vote for the party you like the best, without having to worry about whether other people are going to vote for it too. But some PR systems are better than others. The Electoral Reform Society exists to promote a Single Transferable Voting (STV) system, see http://www.electoral-reform.org.uk This is the PR system that I like the most.
Basics of the system The basis of the STV system is that voters put candidates in order of preference. They put '1' against the candidate they like most, '2' against the candidate they like second best, '3' against their third choice, and so on. Each constituency is multi-member; about four seats per constituency.
The idea behind the system is that if you vote for a candidate who is 'too' popular, i.e. gets more votes than they need to get elected, then part of your vote is transferred to the next candidate on your list.
On the other hand, if you vote for someone who is not popular enough with the other voters to get elected, then once again, your vote is transferred to your next preference.
The counting system itself can be a bit complicated, although computer technology makes it simpler and faster than it used to be.
Advantages This system gives voters maximum control of the poliicians that they elect. If you stand as a candidate, you can't just expect to get in because your party is popular. You have to be popular with the voters yourself. This makes the system more responsive to voters' wishes than systems based on 'closed' party lists (i.e. list of candidates drawn up by political parties).
In fact, STV invites candidates to compete against each other, even if they all come from the same party!
Another advantage is that you elect several people for each constituency. So it's likely that at least one of your representatives will be near to your own situation and political viewpoint.
The system discourages 'splinter' parties (i.e. parties with only a small amount of popularity, spread out over a large area). This usually prevents fascist or other extreme parties getting their candidates elected. It also reduces the likelihood of a very small party holding the balance of power and thus wielding a disproportionate amount of influence, as sometimes happens in Israel.
STV is used in the Republic of Ireland, which is a wealhy country nowadays. The system is liked by the voters. It's not so popular with the politicians themselves, because it forces them to work hard and listen to the voters, which - as almost any part of the world - they are reluctant to do.
The main disadvantage of STV is that because there are several representatives for each constituency, the geographic size of constituencies can be large. Not so much of a problem with the Republic of Ireland, which is fairly small in area, but it could be seen as a problem with Britain or the USA. There is a way to mitigate this problem, by varying the number of people in constituencies, but the problem can't be avoided altogether.
The 'bootstrap' problem But that's not the main reason why Britain and the US haven't adopted STV. The usual problem is that the existing representatives got elected under the present system, so they are reluctant to change it. They don't know whether they're going to be as lucky at election time if the system changes.
Also, many representatives may not like the idea of being forced to work hard and listen to the voters. Although some of the more principled politicians might prefer to do this, rather than just brown-tonguing the party leadership.
Party leaders and high-ups lose some of their power, because under FPTP, voters have to choose an 'official' candidate from one of the two largest parties in the constituency most of the time, or their votes will be wasted.
Hence, voters usually only vote for the official candidates from the big parties. This, in turn, forces candidates to look for endorsement from such a party. By threatening to withhold party endorsement, the party leadership is in a position to twist arms.
With STV, on the other hand, if the voter's first choice can't get elected, the vote is simply transferred to the voter's next choice.
Also, FPTP tends to produce two large parties most of the time, with voters sometimes forced to vote for a bad party in order to avoid one that's even worse! I.e. you might have to vote for a party that goes to war against Iraq, in order to avoid one that proposes a polite form of genocide against gypsies. This feature makes FPTP quite popular with those party leaders who may want to do things like going to war against Iraq!
Another feature of FPTP is that it often - though not always, as we've just seen - produces exaggerated majorities. A little bit of extra popularity, under the British system, can give you (say) a majority of 161. If you're party leader, that means that you're unlikely to lose a vote in Parliament. And that, in turn, allows you to join the USA in a war with Iraq, have suspects imprisoned on 'reasonable suspicion' without the inconvenience of presenting evidence at a trial ... or do almost anything else that takes your fancy.

Tony Blair's Labour Party twice promised to consider introducing a more PR-like system for UK parliamentary elections, but went back on these promises. On a more positive note, the Labour Party has brought in PR systems for regional assemblies - although for some strange reason, they've always chosen a system that turns representatives into 'party poodles' and maximises party power, rather than bringing in STV.
Do you think that might have anything to do with the Labour Party leadership wanting to maximise its power, and not get challenged when it does something unpopular, or am I just being cynical?
Never mind, the introduction of new systems, albeit not the best systems that could have been chosen, has got rid of the idea that FPTP is the system that we've got to have, because ... uh ... it's the system that we've got!

I hope you in the USA get some form of STV for Congress some day, it would definitely help to keep your representatives under control. I know that STV has sometimes been used for state governments.
Oh, and by the way, STV is very good at sharing out power equitably between ethnic groups, and avoiding racial domination. Which makes it unpopular with some.
