Obama has been above 50 percent in some polls. That indicates to me that he probably HAS closed the deal, or very nearly so. He and a democratic Congress will have a devastating effect on the country they secretly hate. Wait till we all see what they do to try to turn us into a country they can love.
He has never been above 50 in a poll that had a true sample of Dems (i.e., any poll having 35-37% Dems, 35-37% Republicans, and the balance independents.) If you look at the samples, the ONLY time he has gotten over 50% is when they have out-sampled Dems by 10%.
