Barack Fails to Make Gains With White Voters in Ky.

Barack Obama showed little evidence that he's been able to make amends with white working-class voters, exit polls in Kentucky show. Whites make up about 90% of the state's electorate, and Clinton won 71% of their votes, including three-fourths of those who didn't complete college. In addition, only about 40% of working-class whites said they would vote for Obama on a national ticket; an equal number said they'd vote for John McCain, the AP reports.

Clinton won 80% of rural voters, who make up nearly half the electorate, and by a smaller margin among suburbanites, CNN notes. Obama won among urban voters, but they make up only about 10% of the electorate. About 55% of voters said they thought Obama shared the views of controversial pastor Rev. Jeremiah Wright. Nearly two-thirds of voters said the economy was their top concern. (Read more Hillary Clinton stories.)
