Democrats Spar in New York The four remaining presidential candidates take part in the last Democratic debate before Super Tuesday, when 10 states will choose their candidates. The debate took on a contentious tone, with moderators and candidates interrupting one another often. A complaint from Sen. John Kerry that he had been cut short brought only the response, "This is New York." The debate was sponsored by The New York Times, CBS and WCBS. NPR's Scott Horsley reports.
