You know, I thought about whether she would offer him the spot, but I came to believe that Hillary realizes Obama would take the attention away from her. She doesn't want people voting for Hillary/Obama, but only for Hillary. She doesn't want some VP who will be out in public like a spotlight, but a second fiddle who will be in her shadows. Just my 2 cents.
I agree up to a point. Hillary does need some help on the ticket in terms of national security credentials. Wes Clark may be the outside choice or Richardson. However, if Obama offers a strong challenge in the primaries, the Dems may be forced to put him on the ticket to placate the black vote, which they will neet to turn out in great numbers to offset Hillary's polarizing effect.
