After at least six months at the top of my Netflix list, I finally received the first season of Borgen, the Danish series about politics in its government "castle" [borgen]. It's so much better than either the British or American programs, House of Cards.
The American version is just incredible, particularly because the competitions for presidential and congressional leadership are separate and different. The British version is more believable because intra-party fights do occur in British politics. But Borgen has the advantage of being set in a multi-party parliament, where there is constant jockeying for power, and the prime minister is not necessarily chosen for government leadership qualities.
Try it... if you can wait for the discs.
