Conservative / Republican
Progressive / Democrat
The last 4 groups overlap with us "none of the above" folks to whom the US gov. and its allies look like Criminal Anarcy.
Plus there's the "stay at home on voting day" folks.
I daresay that in the US, people who have given up on the Repub-Demo Paradigm outnumber those who subscribe to it.
Also some groups aren't listed, e.g. Green Party.
Since the US gov. is Fascist, I think it would be more correct to list an anti-Fascist category.
