So why wouldn't Russia given (a) how bad the sanctions are, (b) the threat of NATO and (c) their desire to reclaim Baltic states do everything in their power to hack voting machines ?
And given this is state sponsored hacking what could possibly stop them ? Especially given that China managed to steal F-35 information despite surely some of the most stringent security controls around.

A viral claim that Trump won because 300,000 voters were turned away due to insufficient identification: http://www.snopes.com/300000-wisconsin-voters-turned-away-du... (Definitely not true. That was an estimate of the total number of people that might not have suitable ID under a law that was overturned. If I recall correctly, the estimate had some issues too. Also, Trump performed much better than expected amongst the demographic that was supposedly being turned away to win him the vote.)
A bizarre viral tweet asking people to contact the DoJ, together with a claim that more votes were counted for President than cast in one county in Wisconsin: http://www.snopes.com/audit-the-vote/ (Apparently the initial reports are just based on phoned-in results that are checked later, and someone misheard.)
A claim by Greg Palast that Crosscheck was used to rig the vote by purging the registrations of enough black voters in Michigan, Arizona and North Carolina to swing the vote. Not on Snopes, but the proposed mechanism wouldn't work - Michigan only purges voters on the list if they fail to reply to a posted notification and then don't vote in any elections between this one and January 2019, and the other states should have similar safeguards by federal law.
