Votebeat has this piece on the alleged voting irregularities, which Charles Stewart debunks:

The case against Rockland County, New York, claims that there were irregularities in the county’s vote tallies, judging in part by what the plaintiffs characterize as statistical anomalies — notably the mismatch in support between Democratic Sen. Kirsten Gillibrand and the person at the top of the party’s ticket, Vice President Kamala Harris. Gillibrand won the suburban county by about 8,000 votes, while Harris lost to Trump by more than 17,000….

A state court dismissed most of the plaintiffs’ requests in March, but Justice Rachel Tanguay is allowing discovery in the case to proceed after the county Board of Elections acknowledged it might amend its response….

In a recent blog post, Charles Stewart III, an MIT professor and well-known election expert, carefully broke down the precinct-level data for Rockland County and said he found no signs of errors or manipulation.

Examined closely, Stewart wrote, the anomalies are mostly centered on a small number of polling locations in the town of Ramapo. There, he wrote, many members of Orthodox Jewish communities supported Gillibrand, but declined to support Harris, which explains the gap.

“The Rockland County election results in this case are a nothingburger,” he wrote unequivocally.
