The russians gained nothing with the wiki leak. It benefits the russians to blackmail hillary if she would win the election. I think the russians would prefer hillary 100X more than Trump.
The content of the emails is the real issue, the source is the democratic party. They own this mess, but in true democratic fashion they are always the victim. For them there is no cop murderer, the murderer is the victim, there is no drive by gansta shooter, it is the gun to blame, that woman (lewinski) was the problem, not bill clinton. Always a finger pointing away from the real problem.
Likewise Trump is the master of doom, and pointing out the ilk in the world makes him a bully, and hillary's record makes her the victim.
