WASHINGTON -- Two national polls out today have different views on a general election match-up between President Obama and Mitt Romney.
In the Gallup daily tracking poll, Obama and his likely GOP challenger are locked in a statistical tie with Romney leading among key independent voters.
In a CNN poll, Obama leads Romney overall by 9 percentage points and by 5 points among independents. He also has a huge advantage among women voters.
The Gallup Poll has a larger sample (2,265 registered voters vs. 1,015 adults including 910 registered voters in the CNN/ORC International poll) and its surveys were conducted over a longer period (five days vs. three days for CNN).
We'll look at the Gallup Poll first. Romney leads Obama 47% to 45% among registered voters. The likely GOP nominee has a 6-point edge among independent voters, who are typically the swing group in presidential elections.
As expected, Obama and Romney are supported by an overwhelming majority in their respective Democratic and Republican parties. Both get 90% support among the registered voters in their parties in the Gallup survey.
In the CNN poll, Obama leads Romney 52% to 43% among registered voters. The president leads female voters by 16 points in the CNN poll, which was taken two days after Democratic strategist Hilary Rosen made a dismissive remark about Ann Romney.
The CNN poll also has Obama leading Romney, 48%-43%, among the crucial independent voters.
Gallup began its daily tracking of the Obama vs. Romney race after GOP presidential candidate Rick Santorum, Romney's chief rival for the nomination, suspended his White House bid last week.
Newt Gingrich and Ron Paul are still running for the GOP nomination. Romney has a commanding lead in the delegates needed to become the party's standard-bearer, and has already started taking some steps with the general election in mind.
The Gallup daily tracking poll, taken April 11-15, has a margin of error of +/- 3 percentage points. The CNN survey, taken Friday through Sunday, has a margin of error of +/- 3 percentage points.
