that nobody hacked them?
Here's an article recently published where some hackers were able to hack into machines quite easily.

You're telling me that even though the machines are easily hacked, etc., because there's no evidence of hacking, they weren't hacked? For one thing, how can you even know if they're hacked or not? Is the hacker going to tell you? The vote is NEVER verified in this country. With some machines it's impossible to verify them (touch screens where there's no paper). In the others they're just never verified as far as I've been able to find.
I live in Wichita KS and a statistician here at Wichita State, Beth Clarkson, working for the Natl Institute of Aviation Research, NIAR, decided to do her own exit polling and compare the exit poll results with the machine results and statistically analyze these results to find out the odds of any discrepancies happening. Kris Kobach would never let her look at any of the paper to see why certain unusual results were happening here and around the country. She set up her own exit polling in 6 precincts in KS during the 2016 election and the title of her first article after she'd analyzed the results was this: "Our Vote is being rigged. What are we going to do about it?"
I would venture to say that if any competent statistician did exactly what Beth did anywhere in the country he/she would find out exactly what Beth did. The vote is being rigged. Here in KS it seems to favor the libertarians more than the Repubs. It's probably different in different areas of the country, but the rigging is taking place and has been since at least 2002. And now with the Russians, whose hackers are at least as good as ours and maybe better, people still won't even consider HAND-COUNTED PAPER BALLOTS, which would solve everything, would be cheaper in the long run, and would negate any possible hacking from anybody, including Russia.
Go Figure.
