It's beyond disgusting to me that the "News Bias meter" on the bottom of the article claims this is "unfairly" biased towards the left. Just because it doesn't reflect well towards your side doesn't mean it's biased.
I think that's just a poor UI choice. That seems to be its default position until you vote. Once you've voted for how biased you think the article is, it shows you the "Most Popular Rating" which is currently "Center/Fair".
