Good to see that the Blaxicasians in SC are finally getting rid of their Hillary-addiction and are able to see the light at the end of the tunnel, by feeling the BERN.
Can you read? Clinton is getting 76% of the black vote in South Carolina in this poll. If anything, Sanders is solidifying the white vote, which is where his strength is.
If the margins of error for these polls are 8-10%, the MOE for sub-samples has to be ridiculously high. I don't think these polls are very good.
Very SOUND methodology. You should go back to psych!
Very good news for Mr. Sanders.
I think I'm smart enough to discern a strange sample - which this is. All internet, most "opt-in" and the same people re-contacted at regular intervals. I'm sorry but if you had a background in research you would understand that a 10% MOE is useless.
