People may have noticed that I haven't written anything about the EU election yet, because I generally wait until the final cavasses are out.
But it would help Americans to know that the EU elections (known in Germany as "Europawahl") are essentially base elections. Think of mid-term primary elections in the USA with pretty poor turnout, where only the hardest core of the base comes out, and you essentially have the turnout for the Europawahl, because it's something that is just too far away from "home" for most folks.
Germans definitely vote in high numbers in their national parliamentary and provincial elections, but it's hard to get people to come out and vote for Europawahl.
So, before anyone on any side tries to make a big judgement here, either on the Left or on the Right, you should wait until the final canvasses are in and also remember that the turnout here is comparatively very low for European standards.
