Much has been made about hacking voting machines, and it should be a big deal. However, the reports that software patches have been installed on Ohio machines to flip the election are too good to be true. This would leave a huge trail leading back to the company who did it. Oh please, oh please, let them do something that stupid. This is covered by the 'fool me twice' rule, they got away with it when nobody knew about it, that's no longer true. Keep in mind the DOJ is not in the hands of Republicans this time.
These sorts of scams have to be more subtle then this for them to get away with them repeatedly. Going in and changing the actual numbers could be done after the fact and not be traceable if done properly. Installing actual software ahead of time, no. Most likely they were running a simple money scam, getting paid big bucks for a last minute software updates that didn't do anything.
Then again, the stupidity of corrupt Republicans knows no bounds.
