There are a couple other names still being floated, like Hillary Clinton, Kansas governor Kathleen Sebelius, and Sen. Jack Reed of Rhode Island. (I don't know who that is, but someone saw the Secret Service in Providence. Gasp!)
Seems like there are a few key criteria to consider:
- Demographic appeal. Use the VP to diversify your ticket. Usually this means geographic diversity, although that conversation is a lot more wide open this cycle. If Obama needs a Southerner, I don't think Tim Kaine is the answer. Give this category to Sebelius.
- Complementary Experience. Choose a VP whose strengths offset your weaknesses. For Obama, this probably means choosing a person with better foreign policy credentials. In other words, Joe Biden.
- Fitness for the presidency. Remember why Jed Bartlett said he needed a good man as his VP? "Because I could die." Nobody's talking about this reason very much, because it doesn't really impact the election as much. But who on this list would be ready to serve as president? Clinton, yes. I don't know how you gauge any of the rest of them, but I'd lean towards Biden.
