What is the optimal amount of attention to pay to political news? I've been trying to cut down to reduce stress over things I can't control, but ignoring it entirely seems a little dangerous. For an extreme example, consider the Jews in Nazi Germany - I'd imagine those who kept an eye on what was going on were more likely to leave the country before the Holocaust. Of course something that bad is unlikely, but it seems like it could still be important to be aware of impactful new laws that are passed - eg anti-privacy laws, or internet piracy now much more heavily punishable, etc.

So what's the best way to keep up on things that might have an impact on one's life, without getting caught up in the back-and-forth of day-to-day politics?
