One way to understand politics is to think of political power as a commodity. It can be bought, sold, traded, given, received, or stolen.
In this the gravity model of Far-trader serves well.
Each large state has it's center and it's "penumbra"-the area in which it's political influence is no longer obviously dominate, but remains to varying degrees. The penumbras of different large states can of course overlap. The Frontier Wars for instance can be seen as the result of an overlap between the Imperium and the Consulate-with the various pocket empires and independant worlds attempting to scrape together some measure of independance from the stalemate.
However competition for power differs from competition for other commodities in one way. Politics is more of a zero-sum game. The interest to a business concern in destroying it's rivals is great, but it can often increase it's wealth by increasing the ammount of wealth to be had(for instance discovering a new planet full of hidden mineral resources, no one has noticed before). While this can sometimes be done in politics(by increasing the efficiency of the organization for instance)often one political center can only expand at the expense of another.
