National Journal's Ron Brownstein writes a long column which can be summarized in one sentence. The only group of whites who continue to prefer Democrats are single women with college degrees.
It is Brownstein's belief that Democrats' chances of winning anything significant next Tuesday rests on that outlier group. Someone should do focus groups to determine why a majority of that group - single white women with degrees - should march to their own idiosyncratic drummer when a majority of all other whites prefer the GOP.
Brownstein's column seems to overlook the latest polling which suggests these educated women may be moving into the GOP camp too.
