CLEVELAND, Ohio (CNN) - Democrats Hillary Clinton and Barack Obama sparred with each other over negative campaigning, health care and free trade Tuesday, a week before key primaries in Texas and Ohio
Those contests are must-wins for Clinton if she is to continue to contest Obama for the nomination, as even former President Clinton suggests.
Debating at Cleveland State University, Clinton repeated angry claims from the campaign trail that Obama mischaracterized her stances on health care and NAFTA in political material mailed to voters in Ohio.
