by Stephanie CrosbyIndiana holds its primary election Tuesday.Secretary of State spokesperson Jim Gavin says his office doesn’t make predictions on voter turnout, but judging by requests for absentee ballots, interest seems to be high. Indiana has what some call an open primary, which means voters can choose the Democratic or Republican ballot when they show up at the polls.“Thirty-two-thousand roughly are requesting Democrat ballots, and 38-thousand are requesting Republican ballots," says Gavin, "so there just seems to be more interest this year in participating in the Republican primary based on that comparison to 2008.”Gavin says in 2008, there was much greater interest in Democrat ballots, because of the primary race for President between Barack Obama and Hillary Clinton.
