I have a difficult time believing nobody has yet diaried about this poll (and I apologize ahead of time if they have), but I couldn't find any mention of it on kos.
Anyhow, here's the gist : "A new poll asked people of voting age which Democratic vice presidential candidate would be most qualified to become president if something should happen to President John Kerry. The answer? A Republican: Senator John McCain of Arizona."
Here's the poll. Make what you will of it:
