Eh, again that is debatable. There have actually been loads of allegations of politically motivated votes (which sometimes can be disproved but some votes are just strange). As for singing in a national language, I dunno. I say let the singers choose, as it won't bring too much diversity regardless if done so wrong (take 2012's, there were a few in that countries' language, but it didn't sound too much different from people like Whitney Houston to some extent due to the nature of the song they chose). I will admit one thing though, Eurovision did make me actually like a Jedward song.
