(CNN) - Cindy McCain lashed out at Barack Obama Tuesday, telling a Tennessee newspaper the Illinois senator has waged the "dirtiest campaign in American history."
The comments came hours before her husband, Republican nominee John McCain, was slated to square off with the Illinois senator at the second presidential debate, and are among her harshest to date of her husband's rival for the White House.
Speaking to the Tennessean, Cindy McCain also said her husband would use Tuesday night's town hall forum as an opportunity to correct what she suggested were misleading statements from the Obama campaign.
“What I have found is that it’s necessary to make sure the American people understand what we have to say, what we stand for as a husband and wife, and what we will do for the American people if we’re lucky enough to be elected,” Mrs. McCain also told the paper.
Both presidential campaigns have stepped up the intensity of their attacks, with only four weeks remaining until Election Day. The McCain campaign raised Obama's past relationship to 1960's radical William Ayers over the weekend, prompting the Democratic nominee’s campaign to unleash a 13-minute documentary Web video Monday detailing the Arizona senator’s involvement in the Keating Five scandal.
In an admitted effort to turn the dominating narrative away from the nation's ailing economy, McCain’s campaign also launched a new offensive against Barack Obama's trustworthiness Monday, releasing a new campaign ad that asks "Who is Barack Obama?", and tells voters the Illinois senator is 'lying' about his record.
