SD Exit Polling

More than two decades after a Democratic presidential candidate last carried South Dakota, Barack Obama and John McCain were splitting support from voters in nearly every category.

According to early results of an Associated Press exit poll, neither McCain nor Obama had much advantage in terms of voters' gender, education, geographical location and most categories of age and incomes.

President Lyndon Johnson was the last Democratic presidential candidate to win South Dakota in his 1964 landslide.

Both McCain and Obama were doing a good job of holding voters from their respective parties.

But Democratic Sen. Tim Johnson grabbed crossover votes from Republicans in the heavily GOP state to win a third term in the U.S. Senate.
