From Monmouth University:
Currently, Gov. Romney leads the incumbent by 48% to 45% among likely American voters. Following the first debate earlier this month, Romney held a one point lead. …
About 12% of the poll’s likely voter sample reports they have already cast their presidential ballot in early voting. Among this group, Romney got 44% of the vote to 41% for Obama – an edge which is within the margin of error for this sub-group.
“The debates changed the dynamic of this race. While many observers feel the president won the second meeting, it did not erase the damage incurred by the first one. And it’s not clear whether tonight’s final debate on foreign policy can alter that,” said Patrick Murray, director of the New Jersey-based Monmouth University Polling Institute.
President Obama has a lead among women, but just barely: He is only four points ahead of Mitt Romney. Romney, on the other hand, has a double-digit lead over Obama among men.
Among independent voters, Romney leads by 19 points, getting 52 percent support to Obama’s 33 percent. He also has a higher favorability rating (53 percent) among independents than Obama (35 percent). And when it comes to what candidate independents voters trust to deal best with jobs and the economy, entitlement programs, the national debt and foreign policy, Romney holds a double-digit lead over Obama in every category.
