Documantary, documents, articles, anything. Please prove to me or provide evidence that the US elections (or other western) are rigged. I was aruging with somebody about it and realised I have no hard evidence - I ended up looking like a dick and realised that I can't be purporting something I can't provide evidence for. So I'm looking for any information that you have on the rigging or predetermination of US elections. Thanks.

*edit - historical examples please... I've seen all the proof of this years election being rigged but want evidence to show that it has been happening for decades
