That was my first position on the matter. The pesky lawyer in me came up with the other position. I believe it would be better for the Country if it fell to Biden because it is going to be a hell of a shock anyway. Having it change the party in the office would be seen as a Coup d'etate.
I think Biden would tap Hillary as VP and as I said, I think she would kill him and eat his head like a good Black Widow does.
