Hmmm hard to say. The far majority of Europeans was in favor of Kerry, but Europe is too diverse to come up with clear answers - Danes might have other opinions about this than Frenchmen. A lot of Dutchmen are really disappointed, I can tell you that. However, because Theo van Gogh was murdered on the day of the elections, and the death of Gerrie Kneteman, a famous cyclist, as well that day, the US elections were a bit forgotten. I think the general feeling that Dutchmen have is one of disappointment, but also one of "life goes on". Some are afraid, but that's a minority. Also, you hear some people bitch about the US voting system.
I know this answer is not really satisfieing, but people are aware of what four years of Bush brought to the world, so they feel they are somewhat "prepared". But the hate for Bush is deep, also because the Netherlands is a very liberal country, and the remarks made by Bush and the Republicans about gay marriage, euthanasia and abortion cause a lot of anger by the general population. A lot of people also oppose the close relations our current government have with the US government - that's why it is predicted that if there were elections now, the (socialist) opposition will get some 90 or more seats on a total of 150. But elections are three years away. And until than, it's likely we have to accept the fact our government is a mix of Christian Democrats and Conservatives (Liberals).
