Donald Trump is claiming in his recent speeches that the election is "rigged."
It's unclear what he means by "rigged" -- is it physical tampering (for which there is no proof) or a bias in the media to unfairly sway public opinion (for which there is
plenty of proof), or both.
Regardless, the claim of "rigging" is being treated as one of the worst threats to our democracy ever!

I did some searching, and it seems that presidential election fraud claims were made against George W. Bush in 2000 (mostly related to the Florida recount) and 2004.
