It seems like this gets to the heart of why we have a two party system (and why it might be eventually inevitable) with all the current issues divided more or less neatly down the middle. The system has been going for so long, and become so "efficient," that it has settled into two roughly evenly sized groups of people, because any significant imbalance implies a "superweapon" developing. If we say roughly half the country is of the Foo party and half Bar: If half the Foo party decided they had a problem with the other half and decided to split into their own group, there'd be roughly a quarter of the country in each of those two split parties. But then half would still be Bar, and would completely dominate the government. So despite whatever differences the Foo/1 and Foo/2 party have, it's not worth splitting their identities over, because their differences with Bar are still larger, even if only slightly. Kind of obvious if you think about it, but rarely articulated as well as SSC does.
