I don't understand how a polling agency can release such data. Like, if that is the data you're getting, I think it's time to re-check your shit. Obama cannot get 95% of blacks nationally and end up at 40% in Colorado. It's statistical nonsense and any statistician should be ashamed for not trying to fix this.
Well, they're not really a polling agency -- Gravis Marketing is a political advertising agency, so they're basically just doing these polls to promote themselves. Frankly, I'm not sure it's doing a good job for them.
