You know, you are right. This is the framing of the narrative I have long suspected (and there is plenty of other evidence not related to this hack supporting the theory). It is possible that the DNC had similar oppo research on HRC that is unreleased. I regret the wording of my post because the reality is simply more complex (though I did mention that it was only suggestive evidence, not conclusive proof by any means).

Of course, my bias in accepting a narrative too easily isn't real evidence that the DNC did not act as allies: there is too much existing (confirmed) evidence corroborating that.

And, as mentioned downthread, the DNC could release documents showing that they did oppo research on HRC as well.

But, absent evidence, there's no reason to suggest anything is unreleased.

I mean it would be crazy for them not to do oppo research on HRC either way. How could they have HRC defense docs unless they also have oppo research...

Releasing additional documents, though, brings more media attention to this hack, which might otherwise pass under the radar.
