Worldwide multi-party election

[PJ]

Not even the broad EU electoral coalitions make sense as ideologically homogeneous and united coalitions. Global politics at this this stage could not possibly become homogeneous enough to support even a very pluralistic multi party system.

I mean, even on the most basic issues, this is impossible to construct; how would the gun waving tea partiers in the US be expected to cohabitate with the Australian Liberals, who literally ban gun owners from joining their party, in a center right coalition. Or even the hilarious idea of an alliance between the Republicans and the Tories. I also doubt you could successfully unite all Sunni Muslims, Zionists, Indigenous peoples, and various sectarian interests into respective political groups.
