Democratic presidential nominee Joe Biden outperformed in counties that use the Dominion or HART InterCivic voting machines, according to a data analyst.

“Analysis evidence suggests the use of the Dominion X/ICX BMD (Ballot Marking Device) machine, manufactured by Dominion Voting Systems, and machines from HART InterCivic appear to have abnormally influenced election results,” the data analyst wrote in a report that was published on Thursday.

The data analyst, who wished to remain anonymous for safety reasons, has 30 years of practice in data analysis.
