More Blacks Lean Toward Obama -- Shift in Allegiance From Clinton Could Tighten Primaries in South

From The Wall Street Journal:

Barack Obama's rising poll numbers among white voters in Iowa and New Hampshire are having an unexpected ripple effect: Some black voters are switching their allegiance from Hillary Clinton and lining up behind him too. That could mean a further tightening of the Democratic presidential race, especially in southern states where blacks make up as many as half of Democratic primary voters.
