Obama Vs. Romney Gallup Poll: Oct. 21 Results

Republican Mitt Romney has expanded his lead in Gallup's daily tracking poll to 7 points among likely voters, an increase of a point from Saturday. The 52 percent to 45 percent lead matches Romney's largest of the campaign.

Other recent polls, including a Wall Street Journal/NBC poll released Sunday, have shown a dead heat between Romney and President Barack Obama.

But Gallup continues to trend more in Romney's direction. Romney also expanded his lead to 3 points among registered voters. 

On Saturday, Romney held a 6-point advantage among likely voters and a 2-point advantage among registered voters.

Today's results include polling from last Sunday through yesterday. That means that four days of post-debate polling are factored into the rolling average.
