The third party option is ruled out only because any viable third party ends up being coopted by one or both of the two major parties. For instance many Green Party issues have been coopted by the Democratic Party, many of the Libertarian Party's have been coopted by the republicans. If a third party has even moderate success, heck even has good looking poll numbers, then the major parties take up their issues.Do you see what I am getting at with your party structure and how it effects your election system? birds of a feather etc. you have effectivly ruled out any effective third party option, because such attempts are scuppered by the electoral system itself.
Umm Stuart as I understand the Westminster system you have the same problem with this 15% (hypothetically). For instance in the UK MP's are elected by geographic locations, i.e. how Talyor was elected for Wyre Forest. We elect our representatives by districts, the English do the same. How is there any garuntee that they will represent this 15% and we won't?Ahh. now this is what I wish to deal with. So you would agree that a full {hypothetical} 15% of your populations veiws are irrelivant and not worthy of representation just because they do not all live in the one state?
If you were to have a proportional system this 15% would not represent any district they would represent 15% of your population.
I mean look at the last UK election, the UK independance party won 1.5% of the general vote, they have no MP's. Indeed Labour won 41.4% of the votes and controls 61.1% of the seats. I'm failing to see why Westminster is supposed to give a better representative government. Indeed going by the last election we are closer to being truly representative than the UK.
The only way to be truly representative is to have a government that is elected by direct proportion, i.e. the Knesset. Frankly governments such as those tend to end up fractured and give EXTROIDINARY power to the small kingmakers. For instance Shas has been able to extort massive amounts of funding and government backing for its policies ... even when the vast majority of the populace would like to tell Shas to take a flying leap. Of course the alternative sucks too, having no majority coalition government has a history of courting disaster - like say interwar Greece.
No matter how you build a government, be it a federal republic like the US, a Wesminster Parliament like the UK, or direct proportional representation you end up with disproportionate power and influence. No matter what happens a good portion of the minority will have no tangible effect on the government.
