"The reason they do that is the harvesters, after they gather hundreds or 1000s of ballots, they hold on to them. On election day, in the morning, they start to slowly trickle them in. And you have to remember they have a lot of people. So you have 20, 30 people, and they’re trickling in 20, 30, 5 here, and there, and so forth. Then they wait until the last hour or two, and then that’s when they unload the rest of them. The reason they do that is so that the county recorder will get flooded with an avalanche of ballots. Then they’re under the clock to verify 1000s of votes. It is impossible to verify that many signatures that fast in that short of a time. This is the way it’s always done. I mean, it’s well thought out. I mean, the system is perfect."
