It's a gutsy choice on Biden's part. I think of it as a reverse of Obama selecting an older, known, white male to stabilize his campaign. In this case it's the old, too well known, too white, too male picking a younger female of color who can get out there and provide some energy to balance the perceptions of the main runner. I think it shows some guts in the old boy. Now I've got to hear from my California contacts to see what they think and feel about it.
