Show of Hands

We taught the world how to throw an election.

We've done much worse than hacking to alter an election.

Spread disinformation yes

Obama tried to alter the Israeli election.

Yes, but we usually skip that step and just overthrow the government and install a puppet dictator directly.

We have into other nation's networks everyday.

If by hacked you mean electronic warfare to alter an election? Thats a relatively new phenomenon but most countries use paper ballot systems.

It by hacked you mean classic subversion to overthrow or significantly alter an election? Then yes, asbolutely. Anyone who says no, well, you're in for a surprise. It's practically what US intel does in its spare time.

The US election was not hacked. Even Obama said so.
The hacking or leaking was the DNC and Gmail before the election. That's not the same as hacking the election.
The US has meddled in elections for president of Israel and Great Britain. Overtly and probably covertly as well.
