Tulsi Gabbard is a legend, and would have made an excellent secretary of state. And it is true that 21 states faced attempts of electoral hacking, just not by the Russians. But it's ok, DHS was just conducting drills, and nothing bad every happens when government agencies conduct drills.

Seriously though, doing a portscan on a public facing website is hardly a tangible threat, and was probably done randomly as a sweep of a much bigger range of IP addresses. For that activity to be labelled as "hacking" is completely disingenuous.

The Diebold voting machine vulnerability incident you're thinking of is Finnish security expert Harri Hursti, from the documentary Hacking Democracy by Black Box voting.
