The tables Mike presented at the very first were a little dubious, not that I don’t think there was massive Dem voting fraud which flipped the election. What is the source of these number? Do Sec. of States really record the number of illegal aliens who voted, or the number of dead people who voted? Doubtful.
If Mike wants to be believed, he needs to provide rock-solid citations and evidence, not just nebulous allegations.
That was my impression too, but I did not watch the whole thing. That big chart contains plenty of data that would be very hard to collect.
The information about each voter is derived from the voter registration rolls that indicate who voted, not the ballots. If the rolls don’t have the required info, they can be linked to other government databases that do.
