Often when I read questions here, people often used the word "Europe", and ask what politics are like "in Europe", and how voters are like "in Europe", and how cultural differences influence politics "in Europe".
An example is this sillyness: Why didn't anyone at Volkswagen blow the whistle?
I don't understand these questions. Europe is a continent. It consists of wildly different countries with different people and different political systems and different cultures and different mentalities (despite the existence of EU, which is mostly focused on facilitating trade between member countries).
So my question is, to what degree do Americans think that Europe is a singular political entity? I am looking for polls, studies, etc. that deal with this matter.
