I'm a bit shocked that in Mississippi of all places, Palin leads by only 4 points. Is she really that unpopular, even down South?
Mississippians who answer polls are probably more affluent (and thus
Democratic liberal, in the Deep South) than the general population, MS is a highly racially-polarized state (they went for McCain by only the same margin that NV went for Obama) - and whites are more likely to say they're "undecided" without actually being undecided than blacks. Also PPP has been releasing a lot of results recently that look pretty fishy. I wish some other pollster would start polling states.
Huckabee performing better than Barbour? Has Haley done anything that caused resentment among Evangelicals?
I'd say that's more a measure of Huck's popularity than Barbour's unpopularity.
