Who is Joe Biden's "Other Female Foe"?

Christine O'Donnell, that's who.


Apparently his first female foe was Sarah Palin.

O'Donnell ran against Biden for Senate in Delaware during
the 2008 presidential campaign, and Biden ignored her.

He won anyway, or maybe because of it, or maybe he won
just because he won.

Maybe O'Donnell will get her chance against another Biden in 2010.
