State figures show that through Monday about 78,000 people voted for the May 8 primary. That's compared with nearly 127,000 a week before the 2008 primary when the state's record for primary voter turnout was shattered.
This year's highest-profile race is for the Republican U.S. Senate nomination between Richard Lugar and Richard Mourdock. That's reflected about 60 percent early voters casting Republican primary ballots.
Voters can cast early ballots until noon Monday with county election offices.
