Back in 2000 I volunteered for the Rick Lazio campaign for US Senate, NY vs. Hillary (best I could, as I live a distance from NYC).
I heard these stories about bussing in fraudulent voters in minority areas of NYC, and to some extent in Chinatown numerous times. Some NYC Republicans/Conservatives said they were eye witnesses to these crimes, and reported them. But in democRAT-controlled NY, nothing is ever done about it of course.
There's proof in this video it exists.
I worked on the Renfrey campaign (or however you spelled it). I must say that was one guilt-ridden Democrat in that video. Well, better late than never to wake up to evil.
