No, what it means is that Clinton abandoned the typical Democrat base - thinking, wrongly, that women and blacks and latinos would flood the polling places and she wouldn't need her base.  

And that base DID feel abandoned.  Even Bill tried to tell her - but she moved so far left to please those on the fringe, they felt no compunction in leaving her behind.   It was not a racial vote - except perhaps on her part.  It was an economic vote and worry about making ends meet....something she refused to admit.
