Why a hacker would “hack” into the system is beyond me. For 20 bucks I go twice a year to the county courthouse and purchase a disk with all the information listed. Put it into a database program and, I and my friends, use the data to help get people elected. The information includes name, address (both residence and mailing), whether or not they voted in primary and/or general going back 5 cycles. Other information like precinct number, congressional district number ... lots of stuff is right there, and readily available to anyone who wants it.
Because that’s not what happened.
I would say it helps to add to the cause for Gov't controlling the internet. Once you build up support that our entire voting system is subject to hacking, either factual or not through the media it helps to breed the control mentality.
Throw in all the other hacking, and you see a pattern.
