ABC News’ Sunlen Miller reports: Sen. Barack Obama, D-Ill., told a crowd in Vinton, Iowa Thursday that he’s not going to pull a Tonya Harding on his rival candidates.
"Folks said there’s no way Obama has a chance unless he goes and kneecaps the person ahead of us, does a Tonya Harding," Obama joked, referring to the female skating champion who conspired to harm a competitor during the 1994 U.S. Figure Skating Championships.
"We decided that’s not the kind of campaign we wanted to run," he said.
Obama said his campaign has been trying to point out differences with the other candidates without going negative.
However the Clinton campaign has accused their Democratic rivals of negative attacks throughout the campaign.
The final judge will be Iowa caucus voters in just one week.
