Real threat or false flag narrative?

Are Russians really thing to throw the U.S. election? Or is the Democrat administration in DC building a narrative of excuses to explain away a Trump election win in November?

This strikes me as the kind of stuff from which civil wars arise.

From the Washington Post:

U.S. intelligence and law enforcement agencies are probing what they see as a broad covert Russian operation in the United States to sow public distrust in the upcoming presidential election and in U.S. political institutions, intelligence and congressional officials said.

Why should anyone believe Obama administration investigations after seeing the FBI's sham job over Clinton emails used to in an attempt to clear Clinton's path to the White House?
