You might want to start with a more controversial site name - Democrats versus Republicans, for example, or Liberals versus Conservatives, or Political Revolution, or Revolutionary Politics, or Citizens in Revolt, or 99% versus 1%, etc
As I recall, we had a sort of vote here, and Politicus Maximus won. As for Dems v. Reps and Libs v. Cons...the first is very US-centric but the second might be useful...as long as none of those darn centrists try to barge their way in.
The 99% one would seem to indicate a focus on fiscal politics or even get swept up with the occupy movement, meaning many would write it off, or it may get taken over.
I kind of like Political Revolution...though it would necessitate an overhaul of the theme...maybe more 1700s versus 70s
