The XX Factor: What women really think.

Why I'm Pro-Joe

It's not just the foreign policy chops; he brings some blood (and flab!) and jaw-flapping to a sometimes too-cool-for-school campaign. Voters actually liked it when Bush tripped over his own tongue; when he failed in his battle with blurting, they could relate, and that is the beauty of the Biden choice: He's got the smarts, the experience, and without question could be president. (In fact, watching the Democratic debates during primary season, I always thought that a viewer who came to the exercise cold would have assumed Biden was the front-runner.) But he also brings the humanity that Democrats have not always seen as important. It is.

Though no one has a more heart-breaking personal narrative than he—his first wife and their baby daughter died in a car accident soon after he was elected to the Senate—he sure never talked about it during primary season, showing an Irish Catholic restraint that will be familiar to a lot of the voters Obama needs to win over. And his working-class roots aren't just nice; they're why I fully expect him to know how to play rough and be plenty comfortable in the role of bad cop, taking on the Republican ticket in a way the candidate himself cannot. A guy who commutes home on public transpo every day taking on Mr. Can't Keep Track of His Houses? As we say in the Democratic Party, pas de probleme.
