Look at Hillary in NY; she had no ties there at all. They looked for a reliably Dem seat and got her in...
Caroline has NO plans to run in Mass., would have to move there NOW, in order to run, and no doubt would LOSE there anyway!
This idiot was trying to run in N.Y., but couldn't even make it to the PRIMARY, before she was picked, as a consolation prize, to be an ambassador.
Like it or not, N.Y. is a BIG DEAL, prominent, and also a place to gather not just local, but NATIONAL "celebrity"/name recognition, nationwise, AND the home of a lot of the BIG DONORS!
