From the past two elections:
Ethnic minorities vote heavy for Obama.
Women vote very strong for Obama.
Religious minorities vote heavy for Obama.
Catholics lean Obama.
People with higher education vote for Obama.
People in urban centers high density population areas vote Obama.
Single people and untraditional households go strong Obama.
People 44 and under go strong Obama.
Whites go strong against Obama.
Men vote pretty strong against Obama.
Evangelicals vote heavy against Obama.
People with less education go pretty well against Obama.
People in rural populations go heavy against Obama.
Married, traditional households lean against Obama.
People 45 and over go against Obama.
The difference, it seems to me, is the significantly more diverse coalition of Democratic supporters and a far more homogenized Republican electorate.
As always. In modern history, anyway. Obama didn't create that.
