Officials in Kentucky say turnout has been steady and problems few as voters cast ballots for U.S. Senate and other races around the state.
Secretary of State spokeswoman Lynn Zellen says there were a few reported problems early on Tuesday involving voting machines and changed polling places, but those were resolved quickly.
Turnout has been projected to be about 49 percent statewide.
The Kentucky Attorney General's Office reported 52 calls by midmorning, most of which involved procedural questions or issues with residency. Spokeswoman Allison Martin said a handful of calls came in with complaints about alleged vote buying or electioneering. Two calls came from Barren County, both regarded procedural questions.
County clerks reported small problems, including a voting machine in Paducah that jammed and a brief power outage in the Fancy Farm area of western Kentucky. Both issues were resolved.
