Although Hillary Clinton continues to hold a statistically meaningful lead over Barack Obama, Obama’s Tuesday speech on race appears to have helped him limit the damage from the controversy over racially divisive remarks by his ex-pastor, according to Gallup’s daily tracking poll. Clinton had a 49 percent to 42 percent in yesterday’s poll, but Obama narrowed that today to 48 to 43 percent. The poll was conducted March 17-19 and has a 3 point margin of error. Gallup said, “While Tuesday night polling showed no immediate benefit for Obama, the Wednesday results were more favorable to him.”
