Hillary challenges Obama for Ohio

Hillary Rodham Clinton angrily accused her Democratic rival on Saturday of deliberately misrepresenting her positions on NAFTA and health care in mass mailings to voters, adding, ''Shame on you, Barack Obama.''Clutching two of Obama campaign mailings in her hand for emphasis, the former first lady said, ''enough with the speeches and the big rallies and then using tactics that are right out of Karl Rove's playbook.''Obama defended the mailings as accurate and rejected Clinton's complaint as a political ploy. He said that despite her current criticism of NAFTA, she supported the trade agreement when it passed during her husband's administration.The long distance clash erupted as the two Democrats campaigned separately across Ohio, one of two big states with primaries on March 4.Obama has won 11 straight primaries and caucuses, and some of Clinton's supporters have said she must win both Ohio and Texas next week to keep her hopes alive of winning the party nomination. Recent polls show Ohio is close, and Texas closer.Clinton's frustration was evident as she criticized Obama in unusually strong terms - a few days after ending a nationally televised debate by saying she was ''honored to be here with'' him in a historic race between a black man and a woman.She said by his actions, Obama was giving ''aid and comfort to the very special interests and their allies in the Republican Party who are against doing what we want to do for America.''''Meet me in Ohio,'' she said. ''Let's have a debate about your tactics and your behavior in this campaign.'' The two are scheduled to debate next Tuesday in Cleveland.In her criticism of Obama, she asked, ''Since when do Democrats attack one another on universal health care?''Obama had a ready reply to that. ''Well, when she started to say I was against universal health care ... which she does every single day,'' he said.Since late last year, Clinton has consistently attacked Obama's health care plan, saying it would leave 15 million Americans uninsured.Clinton's advisers have repeatedly criticised the Obama campaign's mailings, both of which went out in the last several days.
