I suspect a reason why its not that big news in the rest of the world is that this kind of stuff tend to happen. Germany was without a government for almost 6 months, Sweden is still without a government since 9th September last year, and I recall Iceland has a similar situation last election.
What seems more unique to the US situation is that the political turmoil could results in regular employees not getting paid. If we get to the point that people can't pay rent then I am sure it would quickly turn into emergency that international news agency will talk about nonstop until resolved.
