The National Journal poll, published this morning, shows Obama 47% Romney 47% amongst “likely voters”. It partially discloses the racial breakdown: Romney 55% of the white vote, Obama 81% of the “nonwhite” vote.
The Gallup Tracking poll for the 2cnd reports Obama 49% Romney 45% (previously 50%/44%). Gallup has not disclosed its racial background breakdown.
