While it may be the case that "the Russians dun it" with the DNC hack, it also fails the Occam's Razor test, that being the simplest explanation is the correct one.  The Russians, Putin included, are not complete dummies and Putin in particular has a more than a passing interest in a stable hand on the US milititary along with it's nuclear codes. He also has enough problems at home with an economy in tatters.  It could have been a rogue Russian operation but that gets murky too.  The simplest explanation of direct benefit is the GOP.  Given the historical Luddite status of the RNC though that may fall apart as well.  Just below the GOP in probability would be the Sanders movement although I doubt Bernie would have had anything to do with it.  Again, the rogue operation myopically pursuing a short sighted ideology goal rather than the long game.  I find it utterly ironic that Hillary has taken so much largely justified flack for her email server and gets the Dem's hacked.  Priceless!
