This Just In: Hillary Clinton is a Woman.

Duh. But seriously: there are some advantages to being the only female candidate for President, and Hillary Clinton is not hesitating from using them. However, there are at least two disadvantages.

One is that older women might not go for a woman president:

She is less popular among older, married women who are more likely to prefer a more traditional role for women. Clinton's focus on women this week was a bid to consolidate her support among female voters, who account for much of her lead in many polls.

Then there is the fact that her primary rivals are married...to women:

Clinton's main rivals for the Democratic nomination are not conceding the women's vote. The campaigns of John Edwards and Barack Obama have suggested that their candidates are as strong, if not stronger, on issues important to women, such as healthcare, poverty, and domestic violence.

"As the son of a single mother whose grandmother was the family's primary breadwinner, Barack lived through the struggles that everyday women face," Betsy Myers, who worked in the Clinton administration but is now head of Women for Obama, wrote in a memo issued yesterday. "This experience moved him to develop a lifelong history of standing up for women."

In a July interview with Salon, an online magazine, Elizabeth Edwards declared of Clinton, "She's just not as vocal a women's advocate as I want to see. John is."

Hillary's hurdle may not be Barack or John as much as Michelle and Elizabeth.
