How long before the theories that the Clinton's want Hillary as Veep so they can assasinate Kerry? After all didn't Clinton kill off like 50 people in his rise to power?
It wouldn't surprise me if this was a floater from the Clinton's themselves. Generate some publicity from something they're not really involved much in. Keeps her name out there in the public's mind.
I seriously doubt that Kerry would go this route. I also doubt that it will be Edwards. I suspect it will be another relatively popular somewhat known and well liked Senator or Governor from a battleground state.
