Sbane,
If the data is just for the Louisville metro area, then his overall numbers in the county are very likely much worse. Obama would obviously poll stronger in the metro area than he would in the non-metro portion of the county.
I'd say his Louisville numbers are bad but you are right, his numbers in metro Fresno (though note my point above about his countywide numbers being worse than his numbers in the metro area) are not that bad.
But what to make of Palin's numbers in these two metro areas?

As for Palin's numbers, they don't surprise me much. Places like Fresno and Louisville are her base so if she doesn't put up respectable numbers here she won't do better elsewhere. Some on this forum think Palin is widely unpopular and that she has no chance of winning the nomination but I do believe they are wrong. Though she will be a worse candidate in the general than either Romney or Huckabee.
