The XX Factor: What women really think.

Hillary's Girls Pass the Kleenex and Save the Day

Back when that book All I Really Need to Know I Learned in Kindergarten came out, I thought about how everything I needed to know I learned in my 92 years of dating. And as it turns out, those lessons hold up pretty well in political life, too, in that chemistry and timing trump reason and a common goal more often than we'd like to admit.

Political life does not always mirror the real thing, though: If New Hampshire were an employer and Hillary Clinton a job candidate, she would have been out of contention the minute her eyes filled with tears during the interview. As those Sex and the City women (thank you, Trailhead) and every flesh-and-blood XX knows, men can throw phones and wastebaskets across the office and that's cool, but a woman who lets a tear fall is toast.

Which really might explain - sorry, but the instant Conventional Wisdom does occasionally get it right -- why women who could relate rode to Clinton's rescue last night. In future contests, I'm guessing Obama will refrain from gratuitous, way-beneath-him swipes like "You're likeable enough, Hillary.'' But that still leaves her with the same problem Al Gore had in 2000: What about Bill?
