Math professor, thanks for that article. It deals with several aspects of flaws and sources of possible cheating or error in our current election system (or lack thereof). While some data -- e.g., comparison of e-voting vs. other systems -- may not be statistically signifiicant, that's only part of the story. There are many aspects to the reported abnormalities and out-and-out abuses. That's why a comprehensive investigation of all irregularities and potential election fraud -- including attempts to disenfranchise minority voters -- is needed.
