Did the white vote cost Romney the election? (Hispanic vote, RealClearPolitics)
...if our underlying assumption -- that there are 7 million votes outstanding -- is correct, then the African-American vote only increased by about 300,000 votes, or 0.2 percent, from 2008 to 2012. The Latino vote increased by a healthier 1.7 million votes, while the “other” category increased by about 470,000 votes.
This is nothing to sneeze at, but in terms of the effect on the electorate, it is dwarfed by the decline in the number of whites. Again, if our assumption about the total number of votes cast is correct, almost 7 million fewer whites voted in 2012 than in 2008. This isn’t readily explainable by demographic shifts either; although whites are declining as a share of the voting-age population, their raw numbers are not.
...Had the same number of white voters cast ballots in 2012 as did in 2008, the 2012 electorate would have been about 74 percent white, 12 percent black, and 9 percent Latino (the same result occurs if you build in expectations for population growth among all these groups). In other words, the reason this electorate looked so different from the 2008 electorate is almost entirely attributable to white voters staying home. The other groups increased their vote, but by less than we would have expected simply from population growth.
...(uses Ohio as an example) We can see that the counties clustered around Columbus in the center of the state turned out in full force, as did the suburban counties near Cincinnati in the southwest. These heavily Republican counties are the growing areas of the state, filled with white-collar workers.
Where things drop off are in the rural portions of Ohio, especially in the southeast. These represent areas still hard-hit by the recession. Unemployment is high there, and the area has seen almost no growth in recent years.
My sense is these voters were unhappy with Obama. But his negative ad campaign relentlessly emphasizing Romney’s wealth and tenure at Bain Capital may have turned them off to the Republican nominee as well. The Romney campaign exacerbated this through the challenger’s failure to articulate a clear, positive agenda to address these voters’ fears, and self-inflicted wounds like the “47 percent” gaffe. Given a choice between two unpalatable options, these voters simply stayed home.
As he notes, the final numbers aren't in. But, contrast the above with self-interested parties (such as those who have financial or racial solidarity stake) who claim that the "Hispanic vote" is all-powerful and that the GOP has to pass an amnesty.
