I'll get right to the point.
The Daily Kos just isn't that interesting any more.
There was a time in the recent past where this was a great site to pick up a diversity of opinion (within the constraints of the Progressive movement). Kos now seems to have devolved into a partisan shout-fest, with the majority of postings falling in the category of "My Candidate is better because...".
And surprise surprise - web traffic for Kos is down significantly as a result.
The reason why the MSM focuses on the Horse race is to distract the spectators (voters) away from what they're racing for. The ratio of HorseRace vs Issue postings on Kos would bear that out. Especially when looking at recommended diaries.
I hope this is only a near-term phenomena.
Happy new year to all.
