Long lines of voters formed in Kentucky's second largest city, and election officials called for extra voting machines to be brought in.
Deputy Fayette County Clerk Meredith Watson said the machine vendor, Harp, had some extra machines, which have been deployed.
The Lexington Herald-Leader reports the city secured 30 extra voting machines by midafternoon Tuesday.
Watson said reports of wait times ranged anywhere from 30 minutes to an hour. Based on the lines and the higher-than-expected number of absentee ballots, County Clerk Don Blevins' office predicted turnout well above 50%.
Fayette County is in the 6th Congressional District, one of the nation's most hotly contested congressional races with incumbent Republican Rep. Andy Barr facing off with Democrat Amy McGrath, a retired Marine fighter pilot.
