I'm relatively neutral on Wikileaks/Assange, but this is a stretch. I don't think "illegally leaking documents" counts as a political opinion any more than I should be entitled to asylum because I have a "political opinion" that MDMA synthesis should be legal and got caught for engaging in it.
That's intended to cover things like persecution solely for being a member of a political party.
Everything is political opinion, but the legal standards are much narrower. The idea that I can hold a political opinion that "I should not be arrested for breaking laws", break a law, and then expect not to be arrested because of my political opinion is ridiculous.
