Fascinating data from Nevada: just as Hispanics went overwhelmingly – 64 – 24 – for Clinton, blacks went more overwhelmingly – 80 – 16 – for Obama. I’d say this is a vindication of the Clintons’ racial polarization strategy: force Obama to be the "black" candidate and rely on some white and Latino discomfort to build up their own vote margins. Not a good strategy for the South, but great for the West and California. The Clintons have done the math.
