This account does not match some of the clearer "facts" that have emerged since the election. Specifically, according to the reports I have read, the DNC did not discover the hacking & report it to the FBI who then investigated. The FBI reported it to the DNC, it got caught up in the machinery of the DNC (there were doubts it was even the FBI contacting the DNC), the FBI did not push the issue to make sure it was listened to & then when Hillary was in trouble (that is me editorializing a bit), they started to make it a public issue.Finally,when Hillary lost,after more than a week,Obama decided to make it a serious issue.

Personally, I have some doubts about the constant excuse from "intelligence community" about exposing sources & methods being the reason they can't present a convincing case. I think it is mostly that they simply do not have a case that can stand up to scrutiny, partly because they operate on high-risk probabilities, not the certainty they like to project.
