WORTHINGTON, Ky. (AP) — U.S. Senate candidates Jack Conway and Rand Paul are crisscrossing Kentucky in a final push for votes ahead of Tuesday’s general election.

Paul, a Republican from Bowling Green, made his first stop Monday in eastern Kentucky, a region he has courted heavily throughout the campaign. Conway, a Democrat from Louisville, started the day in western Kentucky and was scheduled to arrive in the coalfields in the afternoon.

The two are running for the seat of retiring Republican Sen. Jim Bunning, a 79-year-old former major league baseball pitcher who opted not to seek a third term.

The election-eve tours by the candidates will mark the final full day of campaigning in one of the most closely watched Senate races in the nation.
