Just out of curiosity, is there a set of rules for what happens if a candidate is assassinated between the convention and the election? Does the running mate take over? Does the second-place candidate? Does the spouse (a la Jean Carnahan) get a try, even if said spouse is Bill Clinton?
I believe the DNC's executive committee has the power to select a replacement candidate. So anyone who is constitutionally eligible to serve as president (e.g. not Bill) is in with a chance. I imagine the DNC would pick Kaine for continuity's sake.
