Sounds like a good poll to me reflecting the true breakdown of America which is 50% Republican. Furthermore, a 6% MOE is very not all that bad and likely means that 80% had a positive response to the President.
The poll was taken immediately after the speech, and the 323 adults interviewed were 50 percent Republican, 23 percent Democratic and 27 percent independent.
Gee, somehow, that doesn't ring true to me.
