I don't think it has anything to do with it. Being Canadian does not IMHO add or remove from the debate. If there is anybody suited to size up Northeastern Elitism it is GWB. Son of Maine, educated at Yale and Harvard. He knows that the problem on the bench is not the diversity of sex or color but of the imagination, The rigid hierarchy of ideas that inhabit the Elite Legal profession dueling out among themselves to see whose philosophical underpinnings will win out. GWB concluided that the problem with the bench is less Harvard/Yale and more Rest of America. Here he has again shown an incredible knack of pissing off just about everyone.
IMHO If everyone is not happy with this pick, then she is the most qualified and least polically motivated decision the prez has done so far.
