@European cv,
Yes, he was a liberal professor, but I do think his comparisons were as accurate as they can be. But since both our party systems and election systems are so different, it is hard to make completely accurate comparisons. Your parties are much wider than ours. He compared the democrats with Arbeiderpartiet (our Labour Party). The Republicans cannot be compared with any of the larger norwegian parties, though. Our Progress Party and the Christian People's Party might have a few traits in common with the Republicans, but there's still a lot of differences.
The party I belong to is called H?yre, which directly translated means Right. But when foreign newspapers write about norwegian parties, they usually call it the Conservatives. It's in favour of upholding the welfare state, through taxes, like the Labour Party, but they want a stronger market economy. I would think that in america it would be considered to be a party close to the center.
I also noticed that in america you call the democrats for liberals. Meaning that the leftwing party is liberal. In Norway it's usually the rightwing or centrist parties who refers to themselves as liberal.
