If i recall from after the 2016 election, Judicial Watch identified voter fraud being prevalent from the only 3 county where they were allowed to scrutinise. Of whichThey Extrapolated from that data that more than 1.5 million votes were probably cast in California that were illegal in 2016.
After they had that data, they then identified Los Angeles County in Particular in 2017 and commenced a court case to get Los Angeles County to comply with it's federally mandated obligations. They won the case in 2019 and this was to result in the removal of 1.5 million voters from there alone. These are people who are dead, moved out of state or had not voted in any election for more than 4 years.
So when someone says voter fraud doesn't happen they'd best qualify that or drop saying it because voter fraud is real and has been going on for a long time.
