Right, did anyone screw with it I think is the question worth asking and answering. It is probably more worrying if there is a vulnerability that a 13 year old in his mom's basement could exploit to affect things than some foreign power.
I still get disgusted that anyone who thinks the federal government, which can't accurately count us or figure out what we owe in taxes, is capable of any of the shit we're empowering them to do. This, the most basic, first responsibility that an elected government has, should be simple, and yet they consistently fuck it up.
The best defense that can be mustered is "the mistake didn't affect the outcome."
Which is just. WTF? We should know down to the individual vote exactly what the count was, instantaneously and accurately.
