CLEVELAND (AP) _ Polite, but pointed.
That was the tone of the latest debate between Senators Barack Obama and Hillary Clinton, held Tuesday night in Cleveland. Clinton and Obama clashed over trade, health care and the war in Iraq. They also traded charges of negative campaign tactics.
Clinton said as far as she knew, her campaign had nothing to do with circulating a photo of Obama in tribal clothes while in Kenya 2 years ago. She said Obama's campaign had used the same type of tactics as Republicans. Obama says his campaign didn't "whine" when the Clinton camp released negative materials.
It was the 20th debate of the campaign, 10 months to the day after the first. It offered Clinton her last, best chance to slow Obama's drive toward the nomination. Ohio, Texas, Rhode Island and Vermont hold primaries next Tuesday, with 370 delegates at shake.
Obama has won 11 straight primaries and caucuses.
