So why some juries would gave high points to Russia?
That would be totally against their instructions.
I didn't say that juries never stray from their instructions, just that there
are instructions. Also, Russia had a lot of things going for it, even though I personally hated the entry. And the jurie are instructed to act not only as a counter-balance to the televote but also as a complement to the televote (i.e. "Vote the way you think the people would've voted if there were no diaspora and neighbour voting involved", among other things).
Juries are introduced because more quality songs would have a chance.
But that's not all they're instructed to vote for.
And what did you want? 400+ points from every country at least 8 points?
No, but a single point out of Italy wouldn't be much to ask for. And it's still suspicious how Italy, Portugal and San Marino all banded together and gave "Euphoria" so little to no points. People were concerned Eastern Europe would be Loreen's fall, but it was the Ibero-Italo Mafia that gave her her lowest scores. The fact that the Italian and San Marinese juries seem to have voted pretty much identically is also a bit suspect.
Your song was the best, indeed, but you must respect that not every country can love it
But you see, as you said, one of the things the juries are supposed to do is to vote for quality songs. You can't possibly think that the San Marinese and Portuguese (and Italian) juries voted "correctly" by giving "Euphoria" such low marks. We know that the San Marinese vote was 100% jury vote, so they gave "Euphoria" 3 points... and
Russia 10. There's also 4 for Azerbaijan, 5 for Turkey and 8 for Moldova. That's some dodgy voting. Portugal's vote was equally strange. 3 for Sweden, 8 for Russia, 6 for Moldova.
Italy pretty much matched San Marino almost vote-for-vote, which looks strange when 2 supposedly independent juries were voting. There's no way the 10 of them came to almost the exact same conclusions. And the differences are probably due to the Italian televote throwing a wrench in their shady plans.
Italy:
12 Albania
10 Russia
8 Germany
7 Romania
6 Serbia
5 Cyprus
4 Moldova
3 Ukraine
2 Denmark
1 Macedonia
San Marino:
12 Albania
10 Russia
8 Moldova
7 Italy
6 Serbia
5 Turkey
4 Azerbaijan
3 Sweden
2 Malta
1 Spain
I'm not saying it's a foregone conclusions. I'm saying there's a plausible possibility. Their jury votes were quite un-jury like. Portugal's was more jury-like, but it also gave Sweden unnaturally low marks, but that might've just been the Portuguese televoters. Italiy and San Marino remain highly suspect in my book.
