Allen Raymond wrote the book on rigging elections. Literally.
It’s called How to Rig an Election: Confessions of a Republican Operative. And in it, he explored the dirty tricks that occur in the dark corners of American democracy, including the one he engineered in the 2002 New Hampshire Senate election that landed him in prison for three months. So if anyone knows whether there’s a kernel of truth to Donald Trump’s assertion that the current election is being rigged for Hillary Clinton, he does.
