Indianapolis (AP) Officials in Indiana are reporting a few minor problems as voters turn out to choose between Barack Obama and Hillary Rodham Clinton in the drawn-out democratic race.

One clerk says democratic ballots had not been delivered to two Indianapolis locations, but voters did have the option of using touch-screen machines at both sites.

Two polling locations did not open on time because inspectors were late in arriving. Both of them are open now.

Many voters already were in line when polls opened this morning, and officials are expecting heavy turnout throughout the day.

A democratic ward chairman in Indianapolis says his polling station could see a 55 percent turnout, compared with to the 8 to 10 percent turnout that is typical for the primary.
