Before we escalate to all-out cyber and/or nuclear war with Russia, will we be seeing any -actual evidence- of anything other than a very dumb phishing link clicking Podesta, or of "hacking" involving anything requiring more skill than a neighborhood high school computer club, much less a nation-state?
Nuclear war? Exaggerate much? This is the same sort of nonsense as claims that Donald Trump accepting a phone call from the Taiwanese president is going to get us into a war with China.
I'm guessing we'll see as much evidence as we did regarding accusations about an Iranian nuclear program from American presidents of both parties, which is not much.
And the opposition—the Republicans—aren't in a good position to complain about nondisclosure given the hubbub about the potential accidental leaking of government secrets via Hillary Clinton's private email server. State secrets are apparently really, really important to Trump supporters.
Although I'm sure the Democrats would much prefer the accused not be allowed to speak at all, Putin's question is still pertinent--is he responsible for Democrat losses at -every other governmental level-, as well? Were the Wikileaks e-mails manipulated or untrue, which has still not been asserted?
This red herring is becoming as dangerous as it is ludicrous.
These questions are red herrings. The important point is that the Russians apparently meddled and did so in a way that affected the election of the most powerful political office on the planet.
To address them anyway though:
(1) Yes, the emails were manipulated into propaganda by packaging them with inaccurate interpretations such as those at http://www.mostdamagingwikileaks.com/. One of the more egregious examples uses an email received from an unknown person to assert that Hillary Clinton is racist. They link to the leaked emails, but I imagine most people would read the bad interpretations and never get around to reading the source text.
(2) Given that some of these races were very close—such as those involving Representative Darrell Issa and Senator Pat Toomey—they could have been easily affected by the release of the emails.
