Politicians have been rigging/stealing elections at the state level for as long as I have been alive. Didn't need a computerized system to do it either, but this may make it easier/cheaper to do.
True, but this is very different. Those types of fraud are what's known as "Retail Fraud". They generally require large numbers of people who are all aware of what's going on. It also generally leaves a trail of evidence (the voters know they've been intimidated, the ballot stuffing leaves paper records, etc, etc) that can be followed to find the perpetrators eventually, if only in the history books.
These new systems allow Wholesale fraud (changing the results of the election in one fell swoop) that can be done by a single person, who needs not have a large amount of money, influence, or know-how in order to accomplish it. Plus, if you read the article, the vast majority of these methods would be completely undetectable after the fact. There is literally no way to determine that the frauds ever occurred!!
