There are more people working for "Wallstreet" in New York (461k) than there are people employed in VT (360k). So yes, a senator from NY will be more in bed with "wallstreet" than someone from VT.
I'm calling BS on this. Representing the interests of New York is _not_ what she was criticized for. It was for booking $600,000 "public" (ironic, it was private and secret) speaking events at Goldman Sachs, and such.
