Obama's campaign denied Clinton allegations of 'dirty tricks.'
WASHINGTON (CNN) - Sen. Barack Obama's presidential campaign is denying a fresh accusation leveled by the campaign of Sen. Hillary Clinton that surrogates for the Illinois Democrat are engaging in "dirty tricks" in Iowa.
Clinton campaign manager Patti Solis Doyle made the charge in a letter to supporters Monday night. "In both Iowa and New Hampshire, we have heard that Obama staffers are berating Hillary supporters on the phone with negative attacks against her," wrote Doyle.
She went on to describe accounts of a negative campaign tactic known as "push polling" - a practice where voters receive phone calls from individuals posing as independent pollsters who instead offer details of negative and sometimes misleading attributes about a particular candidate.
Doyle also said some of Clinton’s Iowa supporters have received calls that direct them to the wrong precinct locations.
In a statement released Tuesday, Obama campaign spokesman Bill Burton called the accusation a "flat-out falsehood."
"Our opponents have promised to stop at nothing in an effort to tarnish Barack Obama's character," Burton continued. "Push polling or tactics of confusion have no place in this campaign and we don't or won't engage in them. Unlike some other campaigns, we want every potential Iowa caucusgoer to participate in the process, no matter who they support."
Tuesday's back-and-forth between the leading Democratic presidential campaigns is the latest in a heightened war of words one month before Iowa voters kick off the presidential primary process.
On Monday, Clinton charged Obama "started running for president the day he arrived in the U.S. Senate," and in his "rush to campaign" has missed key Senate votes.
Obama's campaign hit back, saying he "doesn't need lectures in political courage from someone who followed George Bush to war in Iraq, gave him the benefit of the doubt on Iran, supported NAFTA and opposed ethanol until she decided to run for president."
