The Labour Party rebuilt the country after WW2, implemented a very successful welfare system, and as a result they have pretty much been the most popular party until this day (they are currently in a coalition government and have the PM). The political climate in Norway is generally pretty left-leaning and politically correct (not critizing, just stating facts).

Personally I'm not happy with the current government, but I think the opposition is worse. The loudest opposition party is the Progress Party, which harvests many votes on cheap issues like stricter immigration laws, lower taxes and prices on tobacco and alcohol, etc. Your standard right-wing populists.

Don't know if that answered your question, feel free to ask more. And I live in Trondheim, central Norway and the third most populous city.

Yeah, as a Norwegian, I too find the political situation in America completely abhorrent.
