I'd be wonderfully shocked if she even just qualified somehow....nevermind thoughts of winning.
In fact, I can almost see how the voting will go for her in the semi-final;
We know the song is amazing but possibly a little too leftfield for most eurovision tastes, so I think such a risky entry will score highly with some juries that appreciate something a little different so she'll get the odd "high"'mark.
However, she will lose out big time on getting the consistent lower votes and this will more than likely cost her a place in the grand final. I can see the likes of Poland, Cyprus and Switzerland hoovering up points in the 1-5 range at the expense of Latvia, as they are more "agreeable" and "safe" choices.
Anyway, I will hold my Latvian flag high in Vienna regardless
