[not Obama voters]
It is considered a truism that the election of Barack Obama as President of the United States is a big political and social change.
I saw a statistic that white people voted for McCain by 55% to 45%, white men 56% to 44%. Even more tellingly white Protestants voted for McCain 65% to 35%. We can assume that white Protestant men voted for McCain 66% to 34% -- two to one.
A hundred years ago white Protestant men were the only people in the country who voted. The enfranchisement of women, of blacks, and the arrival of Jews, Catholics, and Asians has changed greatly who votes in the United States. The election of Barack Obama is not the change. It reflects the changes that have been accumulating for a century. The election of Obama is not the change -- it is the result of the changes.
There are places where the whole population is white and Protestant -- Utah, Idaho, the Dakotas, Wyoming, Oklahoma, Alaska. Western Colorado. Those places all voted for McCain roughly two to one.
Curiously there are other places that are also white and Protestant -- Maine, Oregon, Iowa, New Hampshire -- that voted for Obama. So even that reasoning doesn't work.
Another argument is that states with big cities voted for Obama, rural states did not. That works for Oregon and Nevada but not for Maine or Utah.
