I think this is true for most communities as they mature. Issue-of-the-day become more prominent as core topics get discussed to death.

For example, I notice a few people pointing out the higher number of Golang articles that get to the front page, however, this is more due to there being more development and discussion as v1.1 was just released. For other programming languages most common experiences have been shared and novel new ideas become fewer.

I don't really see it as a problem. Most political posts are identifiable by title. Although the SvN ratio may not be perfect, I doubt it ever could be without HN implementing something like /.'s customisation options for topics and the ability for users' to block them.
