The Clintons are joining the Obama campaign for the final stretch before the election.
They appeared with vice presidential nominee Joe Biden in Pennsylvania over the weekend.
Biden denounced what he called "unbecoming personal attacks" on Barack Obama.
"Every single false charge, every single baseless accusation is a simple attempt to get you to focus on something other than what's affecting your family and your country," said Biden while in Scranton, Pa.
But the McCain-Palin campaign seemed to be toning down its attacks over the weekend, instead focusing on the ailing economy.
"All across America, I know that there's a lot of anger right now," Palin said. "There's anger about the insider dealing of lobbyists. And anger at the greed of Wall Street. And anger about the arrogance of the Washington elite.
"We need serious reforms to change Washington. John McCain is going to turn your anger into action," Palin promised.
She also noted her opponents' records on abortion rights, an issue key to social conservatives who initially were lukewarm toward McCain's campaign but have found enthusiasm after the pick of the Alaska governor.
Palin says she and McCain would defend "the culture of life."
"I listen when my opponent gave his unconditional support for unlimited abortions," Palin said. "He said that a woman should not be 'punished' with a baby.
"It's about time that we called him on it," she added.
