(Sigh) The problem (IMHO) is that "absence of evidence is not evidence of absence" as the saying goes.
Elder abuse, whether in Nursing homes, or with "home care aides" where the service is provided to "independent" residents via private or State-sponsored home programs is pretty frequent:
Estimates indicate at least 1 in 10 out of 52 million people, or over 5 million people around the nation suffer various forms of abuse as I mentioned.
Elder abuse affects up to 5 million elders in the United States every year. Find out more elder abuse statistics and how you can protect your loved ones.

If even 1/5th of those numbers involves vote fraud, that is 1 million votes.
That doesn't count elders in family care, who can be cajoled/convinced to vote by a "concerned" relative.
