Here’s a paradoxical picture of post-Obama racial relations: a poll finds that most blacks think Martin Luther King Jr.’s vision has been fulfilled, but most whites don’t.

A CNN poll found that 69 percent of blacks believe MLK’s dream of racial justice has been fulfilled — double the 34 percent who said the same less than a year ago in March. Only 46 percent of whites believe that MLK’s dream has come true, although that is a jump from the 35 percent in March.

Some of the excitement over Obama’s victory has cooled since November, when a majority of blacks said it signaled a new era of race relations. That number has fallen, although most blacks still predict some improvement in race relations.
