Clinton acknowledged that her husband, former President Bill Clinton, who was criticized from within his own party for attacks on Obama, had gotten “carried away” at times on the campaign trail.

The senator also stated that she hopes that, following the South Carolina primary, the tenor of the campaign would change and indicated that all sides should take a step back.

“At the end of the day, we will come together as Democrats,” the former first lady said. “We will be a united and committed party to take back the White House in November.”

Meantime, Obama, who appeared on ABC’s This Week with George Stephanopoulos, refused to engage in what he called a tit-for-tat with the Clinton campaign.

He praised Bill Clinton for his work as president, arguing that he “recognized that we needed to take the old traditional values of the Democratic Party of equality, of opportunity of community and update them for a new era.”

Instead, Obama focused on his message to bring change to the country, arguing that the country is weary of the “slash and burn” politics of the 1990s.

“We still see it in Washington today. It is very hard for us to have a common sense, non-ideological conversation about how we’re going to deal with our energy problems. It’s very difficult for us to figure out how are we going to make this economy work for all people and not just some people,” Obama said. “That is not the Clintons’ fault. It is all our faults in the sense that we have gotten into these bad habits and we can’t seem to have disagreements without being disagreeable.”

Obama also commented on rumors that Sen. Edward Kennedy (D-Mass.) is on the verge of endorsing him.

“I’ll let Ted Kennedy speak for himself,” the Illinois senator said. “And nobody does it better. But obviously, any of the Democratic candidates would love to have Ted Kennedy’s support. And we have certainly actively sought it.”
