The most devastating stat is that only 40% are “certain” for Obama. That means he could actually lose in a landslide, based on a preference cascade.
That shows 16% black support for Romney which seems absurdly high. No Republican has gotten that much black support since Eisenhower in 1960.
Probably the most amazing number in your chart is that Romney (counting leaners) is getting 16% of the black vote! That’s more than twice than in any other poll I’ve seen. If that’s anywhere near the true number and that pattern continues, the ‘Rats are deep trouble - not only in this contest, but in presidential elections and a lot of state elections in the future.
