Indianapolis (AP) Hillary Rodham Clinton has eked out a narrow victory over Barack Obama in Indiana's democratic primary.

The tallies from 99 percent of the Indiana precincts show Clinton with 51 percent to Obama's 49 percent. That margin is a little more than 22,000 votes of the more than 1.2 million cast.

It was a cliffhanger. The outcome wasn't clear for more than six hours after the polls closed. The uncertainty stemmed from slow counting in lake county near Obama's home city of Chicago.

Before the race was called for her, Clinton declared victory and told supporters “it's full speed on to the White House.”

Obama told a North Carolina crowd that he stands “less than 200 delegates away from securing the democratic nomination.”
