Barack Obama maintains his 9 point lead over Hillary Clinton in Zogby’s daily tracking poll of North Carolina and has edged ahead of Clinton in Indiana, although by a statistically insignificant margin. Obama leads Clinton 48 percent to 39 percent in North Carolina with 8 percent undecided and 5 percent wanting “someone else.” The margin of error is 4.1 percent. His North Carolina lead is a far cry from his double-digit days in April. In Indiana, Obama leads 43 percent to 41 percent, a one point gain for Obama since the previous survey, with 8 percent undecided and 8 percent preferring someone else. The margin of error here is also 4.1 percent. The polls were conducted May 2-3.
