Firstly, I'm not convinced this is true. There is at least a plausible chance that Trump could win the US presidential election. Even if he doesn't, the Republican candidate does. Trump's stance on race relations is worse than that of any party in western Europe that stands a serious chance of executive control (apart from possibly Le Pen, although her chances of winning are far lower than Trump's), and the Republican party as a whole is also worse if not to the same extent as Trump. Europe does have individual parties which are worse than the Republicans on race relations, yes, but that's largely because most European countries are multi-party, and even rightwing parties who are mainstream do not tolerate racists, so racists form their own parties and therefore have greater political visibility. In America, these groups still exist, they're just subsumed within the Republican party and discouraged by Republican elites/ignored (arguably less so now), so you don't see them. They can't leave because the American political system can only foster two parties; but worryingly they might actually take control of the Republican apparatus (via Trump).
Norway's oil is from the North Sea and the Barents Sea and is from offshore drilling. Clinton supported offshore drilling until 17th December 2015 when she switched and made public statements against it (arguably because both Sanders and O'Malley spoke out against it). You can probably have this one... if you thank Sanders.
Not at all. There is only one one Western European country where a majority of the public oppose at-whim abortion under 24 weeks (Italy). In any other country, Clinton's positions are entirely centrist/unremarkable insofar as they represent the status quo.
This one is interesting because again, bar Italy all Western European countries actually have more favourable opinions of gay marriage than America does. I don't think this reflects a left/right difference but rather a procedural difference. In America, the overwhelming majority of states were forced to accept gay marriage via the judiciary. In Europe, the judiciary is weak and things have to pass through the legislature. If gay marriage had to go through state legislatures in America, you'd be waiting a very long time.
It's not the every American politician is more rightwing than every European politician; that would be ludicrous. It is true that the average American politician is significantly more rightwing than the average European politician.
