So is cancer.
HN really isn't the place for political discussions. It's even in the guidlines[1].
Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon
OK, yeah, they're fun in a way; and I've made the mistake of participating in a few myself (largely NSA stuff). But the thing is, there are plenty of other forums for discussing politics. There's no real reason for discussing politics here unless it has a specifically technical aspect to it.
Personally, I'd like to see HN get back to a focus on technology and business, and the intersection of the two. If the front-page were nothing but stories about Erlang, D, Javascript, acquisition announcements, new tech announcements, and "Show HN: Rate my Startup" posts, that would be a Good Thing, IMO.
