First: Blaming Russia for interfering in our elections is looking more and more like are herring. That said, it is the corruption and dishonesty exposed by the leaks, no matter their source, that had the largest impact on the last election. It is an opinion shared by many voters as the democrats keep losing seats. The leaks nearly provided hard evidence.
Quote:A WikiLeaks figure is claiming that he received leaked Clinton campaign emails from a “disgusted” Democratic whistleblower, while the White House continued to blame Russian hackers Wednesday for meddling in the presidential election and asserted that Donald Trump was “obviously aware” of Moscow’s efforts on his behalf.
Craig Murray, a former British ambassador to Uzbekistan and a close associate of WikiLeaks founder Julian Assange, said in the report by the Daily Mail that he flew to Washington for a clandestine handoff with one of the email sources in September.
He said he received a package in a wooded area near American University.
“Neither of [the leaks] came from the Russians,” Mr. Murray told the British newspaper. “The source had legal access to the information. The documents came from inside leaks, not hacks.”
WikiLeaks published thousands of emails stolen from Clinton campaign chairman John Podesta, providing a steady stream of negative news coverage of the Democratic presidential nominee during the final weeks of the campaign. Mr. Murray said the leakers were motivated by “disgust at the corruption of the Clinton Foundation and the tilting of the primary election playing field against Bernie Sanders.”
The Daily Mail report noted that Mr. Murray was removed from his diplomatic post amid allegations of misconduct.
Second: The FBI repeadetly told the DNC they were being hacked and they ignored their warnings.
Quote:The D.N.C.’s fumbling encounter with the F.B.I. meant the best chance to halt the Russian intrusion was lost. The failure to grasp the scope of the attacks undercut efforts to minimize their impact. And the White House’s reluctance to respond forcefully meant the Russians have not paid a heavy price for their actions, a decision that could prove critical in deterring future cyberattacks.
Quote:WASHINGTON — When Special Agent Adrian Hawkins of the Federal Bureau of Investigation called the Democratic National Committee in September 2015 to pass along some troubling news about its computer network, he was transferred, naturally, to the help desk.
His message was brief, if alarming. At least one computer system belonging to the D.N.C. had been compromised by hackers federal investigators had named “the Dukes,” a cyberespionage team linked to the Russian government.
The F.B.I. knew it well: The bureau had spent the last few years trying to kick the Dukes out of the unclassified email systems of the White House, the State Department and even the Joint Chiefs of Staff, one of the government’s best-protected networks.
Yared Tamene, the tech-support contractor at the D.N.C. who fielded the call, was no expert in cyberattacks. His first moves were to check Google for “the Dukes” and conduct a cursory search of the D.N.C. computer system logs to look for hints of such a cyberintrusion. By his own account, he did not look too hard even after Special Agent Hawkins called back repeatedly over the next several weeks — in part because he wasn’t certain the caller was a real F.B.I. agent and not an impostor.

There are all sorts of coincidences, however there is scant actual proof just opinions on Russian involvement, especially picking a candidate. One would also need to ask why they would prefer Trump over Hillary and not Sanders. It's more likely they just want to show that western democracy itself is corrupt.
