The Gallup organization has become the bearer of worrisome mathematics for President Barack Obama:
Barack Obama is receiving less support in the 2012 presidential election from some of the white subgroups that gave him the strongest support in 2008. These include non-Hispanic white registered voters who are 18 to 29 years old, female postgrads, and the nonreligious, among others.
The 46% of registered voters supporting Obama today is five percentage points below the 51% supporting him in final weeks of the 2008 election campaign. Similarly, whites’ support for Obama is six points lower than it was in October/November 2008 (38% vs. 44%), and blacks’ is down four points (87% vs. 91%). At the same time, Hispanics’ support, at 67%, is essentially unchanged….
Even if Obama were to regain his 2008 level of support among blacks and improve his support somewhat among Hispanics, he could still lose if his support among whites slips any further. By the same token, even a slight increase in whites’ support could secure his re-election.
