It is actually called we have traitors who would throw the information to Wikileaks. The Democrats are too arrogant to admit the real problem.
I believe there is significant truth in what you say.
I watched it go down, and read it differently.
The Russian hacking meme blew up on the heels of an offhand joke Trump made at one of his rallies. He said, "Maybe Russia can find her emails."
This was at a point in the campaign when the FBI was still actively investigating Clinton's private email server. It had nothing to do with the Wikileaks release of John Podesta's emails to other Dem party operatives.
Those emails proved so embarrassing, that Debbie Wasserman-Schultz was forced to resign as head of the DNC. Hillary and the Dems scrambled to find a patsy to blame it on, and hooked on to Trump's offhand comment to cover their rears.
It was such an outrageous excuse, they've been forced to embellish and reinforce it, week by week. They've now compounded their initial lie so much, that Obama is creating real diplomatic tensions with a foreign country over it.
