When I suggested the Federal Parliaments of Australia and Germany I was not thinking about their voting systems, but more about the members representing the electors through different "constituencies". The Australian one is more immediately relevant as both Houses are directly elected: the House of Representatives by population (numbers of electors) and the Senate by State (fixed at 12 members per State irrespective of population). I would have no problem with electing both such Houses by STV-PR, but I agree that is not how it is done at present in Australia. Because the upper and lower Houses would have different functions and would represent the electors through qualitatively different "constituencies", I don't think there need be any practical political problems in the operation of a Parliament with two Houses, both elected by STV-PR. (As to district magnitude, you'll see from other posts that I am totally opposed to nation-wide PR elections.) > > As a practical matter, if we ever get PR in the US, it will start at the > state level.

I do appreciate the sophistication that can go into gerrymandering. However, the fundamental problem remains that 50% of those who vote will get no representation no matter whether the district is gerrymandered or not. Correct that defect and you can (more or less) forget about gerrymandering. Gerrymandering causes a great deal of concern, but focusing on it deflects attention away from the underlying problem - the voting system is rotten and should be changed. If you think you've got problems with what we call "safe seats", you may be interested to know that the balance of power in the UK House of Commons (659 members) is decided by only 10,000 voters, even when 30 million vote. The policies of the main parties are all focussed on winning the support of those 10,000 voters. Some democracy! James ---- Election-methods mailing list - see http://electorama.com/em for list info
