After 84:
Strong Bush
Lean Clinton
Lean Clinton
Lean Bush
Lean Bush
Strong McCain
Strong Romney
I tend to think of a blue-collar, white, poor to middle class worker from Ohio or Pennsylvania when I think of this.
Could be a working class Irish Catholic from New York or Boston also. I don't think it would be. Strong McCain even by your criteria though given the size of Obamas 2008 victory. In 2012 qa sizeable minority of these voters might have also voted for Obama just because Romney reminded them of there boss.
