That would be pretty solid evidence that the Russians are releasing information to the public, but the fact that they used Wikileaks doesn't support anything. There are a lot of ways to release information -particularly if the information happens to be true.
On a strictly irrelevant note, but because I don't like passively accepting premises I disagree with...
And the idea that the Russians extracted and released those emails is still fishy - if the Democrats win a batch of elections then Russia is going to start looking really stupid. It isn't impossible that the US intelligence services are wrong in their accusations, simply because as plots go it is a totally stupid one. It doesn't make any sense unless considered in context of only 1 election cycle.
If Russia had a magic button to decide elections, the DNC and RNC would have found it too by now. It is much more likely the actions of a rogue troublemaker, not acting on specific instructions to do what he did. Even if he was affiliated with the Russians.
