Sen. Barack Obama is now 2 points behind Sen. Hillary Rodham Clinton in Gallup's daily "tracking poll" of Democratic voters.
She leads 47%-45% -- less than the poll's +/- 3 percentage point margin of error. Gallup says it surveyed 1,227 Democrats and voters who "lean" Democratic from Tuesday through Thursday.
Over the past two days, Clinton's advantage has narrowed from 7 points to 5 points and now to 2.
Gallup writes that:
Clinton moved 7 percentage points ahead of Obama in Gallup's March 19 report and sustained a significant 5-point lead on March 20. Her gains were coincident with the controversy over Obama's former pastor and "spiritual mentor," Rev. Jeremiah Wright. However, the surge in Democrats' preference for Clinton that Gallup detected earlier in the week has started to move out of the three-day rolling average, and the race is back to a near tie. It is possible that Obama's aggressive efforts to diffuse the Wright story, including a major speech ... have been effective.
