Washington (AP) Exit polls of Wisconsin democratic voters suggest Barack Obama is drawing support from some groups that had seemed to be in Hillary Rodham Clinton’s corner.
He ran strong with white, female and working-class voters in Tuesday's primary.
Preliminary figures show Obama with a slight lead among whites and splitting the female vote with Clinton. His strength also came from men and young voters.
Clinton still drew solid support from less-educated and older voters.
On the republican side, John McCain and Mike Huckabee were splitting the conservative vote but McCain had a strong lead among moderates. Huckabee was again doing well with white, born-again and evangelical christians.
