Eloise Harper and Sunlen Miller report: Sen. Clinton speaking to reporters in Cedar Rapids, Iowa, explained her recent move to go on the offensive against her opponents.
"I have been for months on the receiving end of rather consistent attacks -- but now the fun part starts," Clinton said. "We're into the last month and we're going to start drawing the contrast, because I want every Iowan to have accurate information when they make their decisions."
Clinton, up until recent weeks, has avoided going after her opponents, saying that she is running a positive campaign.
Clinton spokesman Jay Carson clarified that Clinton wasn't refering to the "fun part" as going on the offensive, but rather the next phase of the campaign.
The Obama campaign quickly had a response -- a paper statement from Obama:
"This presidential campaign isn't about attacking people for fun," Obama's statement said, "it's about solving people's problems, like ending this war and creating a universal health care system. Washington insiders might think throwing mud is fun, but the American people are looking for leadership that can unite this country around a common purpose, and that's what I'll continue to offer in this campaign."
