Call it the girl power trifecta.

Sen. Hillary Rodham Clinton (D-NY) is getting three boosts today among women voters, who already favor her over any other Democratic presidential candidate.

The National Organization of Women is poised to endorse her 2008 candidacy.

Clinton's campaign is offering supporter and female tennis legend Billie Jean King up in a telephone conference call dubbed the "Women's Power Lunch" this morning.

Also, one-time female vice presidential nominee Geraldine Ferraro sent an e-mail through the Clinton campaign today, urging contributions before Saturday's big fundraising deadline.

"Hillary is poised to break the biggest glass ceiling of them all," Ferraro said. "We can do it. We can make history and elect the leader America needs. Let's tell Hillary we've got her back."

"It's hard to believe that in the decades since I was the first woman nominee for vice president, with all the progress we've made, no other woman has been able to get so far," she continued. "But now's the time."
