This graphic from the NYT is a good analysis of election demographics. It reveals the importance of the Hispanic and Asian vote. What the chart doesn’t do is weight the importance of each sector. In other words, the fact that Hispanics voted in larger numbers for Obama is not a surprise, but it doesn’t tell us their impact by the size of their cohort. But it takes a picture of the electorate that is very telling for the Republican Party.
Men switched allegiance and voted against Obama this time, but not as many as voted for Bush in 2004. Fewer women voted for Obama this time, but still solidly in the “blue.” More “
rich” smart people turned away from Obama. Younger people turned out for Obama; older (and wiser) for Romney. Their is no breakdown for education, which would be an interesting statistic.
You Republicans have a lot of work to do if you wish to remain viable.
