For better or worse? Bobby's one of the few people McCain could run with that could make me vote for him. A good friend of mine was a staffer of his in Congress, and he's definitely the real deal. Super-intelligent dude who's fascinating to chat with, and a heck of a nice guy to boot.
For better. The VP slot will make all the difference as it will define where we will go in the long term future, not just four years.
