I just don't understand the point of these stories:

Fewer Americans believe the presidency of Barack Obama, the first African American elected to the White House, has helped advance race relations compared with a year ago, a Washington Post-ABC News poll suggests.

The poll, published on the U.S. holiday commemorating civil rights leader Martin Luther King Jr., found 41 percent now say Obama's presidency has helped race relations, compared with 58 percent on the eve of Obama's inauguration a year ago who said his presidency would help race relations.

The decline was the sharpest among African Americans, with 51 percent now saying Obama has helped advance race relations, compared with 75 percent who, last January, said they expected Obama's presidency to help.

This is statistical porn. Does it really mean anything?
