Highlights from preliminary results of exit polling Tuesday in the Indiana and North Carolina Democratic primaries for The Associated Press and television networks:

WORRIED ABOUT THE ECONOMY

The economy was on voters' minds in Democratic primaries in Indiana and North Carolina. Two-thirds of Democratic primary voters in Indiana and nearly as many in North Carolina said the economy is the most important issue facing the nation. That's more than have said so in 28 previous competitive Democratic primaries with exit polls this year.

Only about one in five in each state said Iraq was the top issue, and even fewer picked health care from a list of three issues.

Four in 10 Indiana Democratic voters said the current recession or economic slowdown has affected their family a great deal. Nearly as many said that in North Carolina.

CROSSOVER VOTING

Indiana's Democratic primary was open to all voters. About one in five said they were independents and one in 10 identified themselves as Republican. North Carolina's Democratic primary was open only to voters registered Democratic or unaffiliated; nearly one in five voters in that contest called themselves independents.

DEMOGRAPHICS:

The exit poll estimated blacks made up about a third of voters in the North Carolina Democratic primary, about one in seven in Indiana. More than half of voters in both states were women, which is typical for Democratic primaries. About one in seven voters in Indiana and slightly fewer in North Carolina were under age 30; about a quarter in North Carolina and somewhat fewer in Indiana were over age 65.
