Dorothy Rodham's appearances at a series of rallies around the state Saturday are just the start of the effort to move women, a group the campaign has long viewed as its core constituency, into Clinton's column. Kathleen Kennedy Townsend and former secretary of state Madeleine K. Albright will come to Iowa to vouch for her "strength and experience," which her advisers view as her main asset, and even more surrogates will be arriving in the next two weeks.

....Take your buddy to caucus" events have filled Clinton's Iowa schedule in recent weeks. These sessions are aimed at helping women understand the time-consuming caucus process, to drive up their participation rates. Emily's List, the abortion rights group that supports female candidates, has also launched an education program for Iowa women who are inclined to support Clinton but who had not planned to caucus for her. That demographic may represent her best chance for increasing her support.

As for the Oprah factor,

"I think they're going to have some really terrific events with Oprah," [Clinton Strategist Mark ]Penn said. "I think the big question really is, does Senator Obama have the experience, compared to Hillary Clinton? And I don't know how that's going to really change that. I think at the end of the day, she will get more women than anybody else, and I think she will because I think Iowa women will break late for her."
