Every county and county-type jurisdiction in the nation conducts the election in their own way pursuant to the laws of each state (and DC). There are over 3000 counties in the U.S. Some use paper ballots. Some use touch screens. Some use ink punched on cards. None are connected to the internet. All jurisdictions have absentee voting by mail. Many have early voting by various methods. It's a total hodge podge that cannot be hacked.
If the allegation is that the Russians meddled by hacking the DNC and/or Podesta's and/or HRC's emails/servers, I suppose that's possible. But (1) Assange has stated categorically that his source was not Russian, and (2) if the Russians targeted the Dems, to what purpose since everyone expected HRC to win right up until the returns started coming in. And no one forced Hillary Clinton to break the law by putting a poorly secured server in her home.
There is not one single shred of evidence ever published that proves the Russians meddled in our elections in 2016. Yet everyone seems to accept the premise as true. Why?
I used “alleged”. We don’t know what the Russians did or did not do with respect to our elections, but we do know that the Obama Administration was using the allegation of them doing it for political purposes.
