We have a multi party system.
What about a draft? A draft would be good. It could be based on either the number of wins from the previous election or the number of offices currently held. No free agents though.
Well, that applies to the way things are now because of the single member, "first past the post" system we have now. If we had proportional representation, things would certainly be different. There wouldn't be as much call to band together behind one of two leaders or platforms, no matter how deficient or unpalatable. You could vote for a party that more closely represented your views, and that party might be able to govern in coalition with others. So his argument that one has to behave in a certain way now isn't an argument against PR.
Lamb may favor the current way because he wants a polarized, right vs. left party system, but proportional systems still recognize ideological conflicts. Where they differ is in allowing for those whose voices aren't heard in a two party system to have a bigger say in the process of government. That's not always a good thing: small parties tied to unions, occupations, economic interests, and ethnic or racial or sectarian groups can really gum up the works with their demands. But one wouldn't have to choose between two unsatisfactory prepackaged sets of issues.
So would PR be a better system? I doubt it. It wouldn't make party machines, deal makers, and big contributors less influential. It wouldn't make government more accountable to the electorate either, just alter the places where the deals are made a little bit. In countries that are really divided ethnically or regionally, like Israel or Italy, PR simply makes the divisions worse: for all the ideological bluster about the two party system, it does make it possible and necessary for people from different regions, classes, and races to cooperate and compromise for what they take to be the common good. And in any case, we won't scrap our own system for light and transient reasons.
But there have been ways of modifying pure proportional representation. One is to introduce a minimum percentage of the vote that parties have to win to be represented. Another is to divide the legislature between single-member winner-take-all district seats and party list proportional representation seats. So it's not as though the result of proportional systems of representation is always chaos.
This is the biggest pile of bulls**t I've seen on these boards. Proportional representation, with a vibrant multi-party system would add new life to the American political scene. Ordinary people would become interested in politics again, because all, or nearly all, would feel they have a party which represents their interests. All we have now is one party with two poorly defined wings, with a horribly bland, muddled message. The US political system has become so sclerotic, change-proof, and beholden to special (i.e. moneyed) interests, that people are tuning out en masse. And some pundits complain that the major networks didn't air much of the Demopublican conventions! They're INFOMERTIALS for heaven's sake; like watching an hour presentation on timeshares or some kitchen gadget. People would flee with their remotes to cable channels and the nets know this. Sorry for the rant, but the left wing of the Demopublican party kept Ralph Nader off the ballot in my state. Oh, the agony.
