WINTERSET, Iowa - Hillary Rodham Clinton was joined by her mother and daughter Saturday as she vowed "change across the generations" and stepped up her pitch to the women voters who could hold the key to Iowa's caucuses.

"We're getting close to the caucuses," said Clinton. "I always think it's better to go to the caucuses with a buddy. Today, I've got some buddies with me."

Those "buddies" included 88-year-old mother Dorothy Rodham and 27-year-old daughter Chelsea Clinton, making her first appearance with her mother on the trail in the race for the Democratic presidential nomination.

Opening the swing, Clinton noted that her family is able to care for her mother as she ages.

"I'm fortunate, my mother lives with Bill and me," said Clinton. "Lots of times she has more energy than we do."

Clinton noted that her mother fits the description of women who were born before women got the right to vote, and are now pushing to elect the first woman president.

"She has seen a lot happen and change in our country," said Clinton. "Not everyone is as lucky to have their mother or father or grandparent with them as we are."

Clinton's mother joined her on the campaign trail Friday night, and Chelsea, who works in New York City's financial sector, joined her Saturday morning. Neither spoke at the campaign events, but Chelsea worked a crowd hard as they opened the day.

Clinton used the occasion to trot out a plan to bolster long-term care, including a $3,000 tax credit for caregivers, a doubling of the standard deduction for the elderly and a tax credit for purchasing long-term care insurance. She repeatedly pointed to her ability to care for her own mother as she ages.
