Clinton declared winner of South Dakota primary

While the other two big cable news networks were calling the Democratic presidential race itself, for Barack Obama, Fox News was declaring Hillary Clinton the winner of South Dakota's Democratic primary.

As of this post, CNN and MSNBC were still waiting to make the South Dakota call. Exit polls from the state have indicated that Clinton has an advantage over Obama there.

Update: CNN and MSNBC have now called South Dakota for Clinton as well.
