I flagged this. No politics on HN, not even from PG.
The distinction is subtle, but I think important. For instance, an article on Romney's attempt to take all sides on all issues so as to appeal to whatever audience he is speaking to at the moment would be inappropriate politics if the theme of the article is that Romney's campaign is setting the record as the most dishonest campaign in Presidential history.
On the other hand, if the theme of the article was that in the age of the internet, when we have near instant access to news, and anything a politician says is widely reported, you might expect that the "all things to all people" approach would be a terrible failure, and yet it is working well for Romney, and so the article tries to explore WHY this is so, I'd say that would be quite appropriate for HN. It raises an interesting question of whether widespread access to information actually helps people make better decisions, or just makes it easier for them to find information to reinforce their preexisting beliefs and contrary information gets ignored. It could be the launching point of some very interesting non-political discussion.
