You might want to look as the official Kentucky voting results website:
I don’t see the absentee number on there ?
I heard the top elections official in Jefferson County giving the number of absentee, mail-in, and early voting totals for the county on Monday. He said there were about 680,000 registered voters. Around 45,000 had voted early. The mail-in number was around 4,000. The absentee voters (who vote early, in person, for cause) was in the hundreds. It was really small.
Early voters still have to show a photo ID. I can’t imagine that fraud in this way could be very high.
