I don't believe there is such a term as «political voting». What does it mean? Cultural and neighbouring, yes, but political? What does Hungarian politics have to do with Finland? If anything, it was «cultural voting» because their languages are in the same group, but even that is one hell of a stretch. Maybe they just, oh I don't know, liked the song?
I was ashemed of Norway's points this year, we gave 7, 8, 10 & 12 to Nordic countries. The reason we «always» give Sweden or Denmark 12 points is not because of politics (honestly, how could it?) but because they're our neighbours with a lot of «immigrants» from those countries here, and we generally have the same musical taste.
The reason there was so much bloc voting this year was because there was no clear winner, I think.
I expect Ireland to come high in the televoting this year. It's interesting that you see Italy winning the jury vote... somehow I think maybe it won the televote. But I'm probably wrong as always.
