LOUISVILLE, Ky. (AP) -- Polling places opened their doors across Kentuckiana.
Polls opened at 6 a.m. in Indiana and Kentucky, and are open until 6 p.m. local time.
Kentucky Secretary of State Alison Lundergan Grimes has predicted a record number of voters will cast their ballots.
Besides the presidential race, Kentucky has a competitive congressional race in central Kentucky. Voters also will choose state legislators and decide whether hunting and fishing should be a constitutional right in the state. Voters in eastern Kentucky will choose a Supreme Court justice.
Voting Hoosiers will choose a president, U.S. senator, nine members of Congress, 25 state senators and 100 state House members.
Voters in both states can help keep tabs on Tuesday's election.
Staffers in Kentucky will answer an election fraud hotline beginning at 6 a.m. EST so that voters who see any irregularities can report them. The hotline number is (800) 328-8683.
Indiana voters may call 866-461-8683 to report any irregularities.
