Bill Richardson would have locked up New Mexico, Nevada, and maybe Colorado for Obama.
Tim Kaine might have locked up Virginia for him.
A credible female candidate (maybe Feinstein) would have generated even more buzz and excitement from the MSM and the Libs about the "groundbreaking" nature of the ticket, and probably would have increased his margin with women.
I'm sure Biden will do some good for the ticket, but it is hard to believe that with so many intriguing options available, Obambi settled on Hair Plugs from Delaware.
Biden is such an idiot he said yes, lol!
