Conventional wisdom says that women voters are naturally drawn to Hillary Clinton, but Barack Obama and John Edwards are in no way ceding this ground to Hillary.

Both campaigns have established “Women for Obama” and “Women for Edwards” groups, and both Michelle Obama and Elizabeth Edwards are helping their husbands target women voters. On May 15 John Edwards held an Iowa women's town hall in Des Moines, the same day that the campaign released a list of 1,500 Iowa women who have pledged to caucus for Edwards.

Tuesday's Des Moines Register included a story about Michelle Obama's event the previous day at a coffee shop in the suburb of Waukee.

This passage caught my eye:

Nancy Bobo, a Des Moines Human Rights Commission member, attended the Waukee event. She said Barack Obama has her caucus vote.

“I don't think there's any other candidate that on Inauguration Day can get up and speak to the world and immediately the world knows it's a new day in America,” Bobo said. “We're electing a president, not just for Americans, but for the world. … We need someone that will really bring people together.”

I remember Nancy Bobo from the last caucus campaign. She was one of the key organizers of Women for Kerry, which held regular breakfasts for professional women and other events. After the 2004 campaign, Bobo and other organizers continued to hold these events, renaming the group Women for a Stronger America.

Among Iowa Democrats, Nancy Bobo is not as well-known as Clinton supporter Bonnie Campbell or Edwards supporter Roxanne Conlin, but this is still a big catch for the Obama campaign, in my view. A lot of professional women in Des Moines and the suburbs know and respect Nancy Bobo. Her backing may well persuade others to give Obama their serious consideration, or to give him another look if they had been leaning toward a different candidate.
