The humorist and cartoonist Scott Adams:
"If you want a reason to be worried, ask yourself why the mainstream media is so keen on framing the election as “not rigged.” The message I’m getting from them, collectively, is that they think it will be. (Because it will be.) We just don’t know how much the rigging will matter.
Why do I say it will be rigged?
Because whenever humans have motive, opportunity, a high upside gain, and low odds of detection, shenanigans happen 100% of the time. Our vote-counting systems have plenty of weak spots. Rigging (to some degree) is a near guarantee.
And keep in mind that Team Clinton has framed Trump as the next Hitler. That gives every citizen moral cover to do outrageous things to stop him. The stakes are sky-high. In this environment, it would truly be a miracle to have an unrigged election. But again, we don’t know how much rigging there will be. It might not be enough to matter.
There will almost certainly be election rigging for the same reason there has been debate rigging. If you don’t believe me about debate rigging, ask a woman who did some of that debate rigging herself. Allegedly. Unless it was Russia’s fault."
