Something both Democratic and Republican woman can agree on: Power in the hands of women is a good thing – and more power is even better. So Tuesday’s book party for Melanne Verveer and Kim Azzarelli, was packed with dozens of Washington businesswomen, philanthropists, diplomats, journalists and other power brokers.

Ambassador Verveer, former chief of staff to Hillary Clinton and longtime advocate for women’s rights, and Azzarelli, an adjunct professor at Cornell Law School, are the authors of “Fast Forward: How Women Can Achieve Power and Purpose.” The book is a part inspirational, part workbook on leveraging women’s economic power for global good, something that Verveer said is finally possible.

“We’re got more women in positions of power at all levels,” said Verveer, the former United States Ambassador-at-Large for Global Women’s Issues,”I think we’re at a tipping point, an historic moment, a power shift — there are things happening in our society that may not blossom fully unless we seize the moment.”

The party, at the home of Donna and Mack McLarty, drew an impressive list of Washington’s A-list names: Adrienne Arsht, Ann Jordan, Nina Totenberg, Catherine Reynolds, Samia Farouki, Marlene Malek, Elizabeth Bagley, Alma Gildenhorn, Rima Al-Sabah, Lucky Roosevelt, Ann Stock, Buffy Cafritz, Sally Quinn, Wilma Bernstein, and others. Hillary Clinton, who wrote the forward to the book, would have been there — but had another engagement Tuesday night.

Is it safe to say Verveer is supporting her former boss for president? “I think it’s fair to assume that” she said with a laugh.

So the timing of the party — just before the first Democratic debate — seemed odd until McLarty, one of the night’s hosts, revealed his method behind the madness: “It means everybody will leave by 8 o’clock!”
