There has been a grand total of one non-internal poll from this race since the start of October. One of the most competitive races and very little polling, what gives?
Polling in general is in a pretty fast decline. 2014 had roughly double the amount of polls 2018 has had, 2010 roughly triple.
Why is polling in decline?
Probably a combination of a few things. Big polling misses shaking confidence in the industry, the decline of the media in general leading them to cut costs (polls cost money), aggregators like 538 and RCP making individual polls less impactful, etc.
