World Election

[izixs]

I'd argue that some of the party organizing would be determined by the exact form of the world government as well as how the world government came about.

A parliament style legislative body would of course encourage during the first few decades a good deal of small parties that might over time congeal into larger parties, but that in the mean time are fine in their lose coalitions. While a body more akin to the the US system (hopefully sans electoral college... but it could be fun, if impractical to give all current countries electors) would probably lead to a few parties dominating, perhaps in regional patterns.

As for the other factor, if the world government came about via careful negotiation and little else, expect a good many parties to appear that actively support disillusionment of the government and who will not join a governing coalition that doesn't support that view. This can lead to problems as the rest of the pie might be very small  with no clear ideological based coalition really gaining the support it needs to carry out an agenda. Instead you might have a weird match up of globalist conservatives hanging out with international communists in a coalition just to hold the country together for a chance of enacting one of their agendas down the road.

On the other hand, if the world government was formed by force, there'd likely be a governing party for a while at least that either goes away by its own choice or the government is torn apart as the world revolts. Either way, a very unstable situation.

Another option is the world government formation caused by external threat. Perhaps it becomes obvious that in ten years 3 billion people will die from the effects of global warming unless we do something asap. Or perhaps we suddenly realize we have been noticed by an interstellar empire that might want to do nasty things to us. Or a series of smaller things push the world together in a similar fashion but less dramatically. In this case it might be very popular to be pro-world government as those against it will be labeled as wanting people to die. In which case normal-ish political concerns will take over after the primary crisis.

So, how does the world get to that world government and when its there, what does it look like?
