Obama rises in polls after convention

President Obama got a modest bounce from last week’s Democratic National Convention, pulling ahead of Republican challenger Mitt Romney, according to polls released Monday by CNN and Gallup.

Obama leads Romney, 52 percent to 46 percent, among likely voters in a CNN survey taken between Friday and Sunday, the three days after the convention. A poll taken in the four days before the Democratic convention -- which were also the four days after the Republican convention -- showed the two candidates tied at 48 percent.

Gallup’s daily tracking poll, an average of the previous seven days, gave Obama a 49-to-44 advantage over Romney on Monday. A week ago, the president led by a single point.

The Gallup poll had a margin of error of 3 percentage points, and the CNN survey had a margin of error of 3.5 points.

The CNN poll indicated that the Democratic convention helped to improve Obama’s favorability rating significantly and push Romney’s below where it was before the Republican convention. In the poll taken between the two parties’ conventions, Obama had a plus-3 rating and Romney had a plus-10 rating.

The new poll showed Obama with a plus-15 rating and Romney with a plus-1 rating — lower than the plus-4 rating the GOP nominee had before his convention.

Obama also made some gains in likely voters’ confidence in his ability to manage the economy, according to the CNN poll. Before the Republican convention, Romney led Obama on handling the economy, 50 percent to 46 percent, and he widened the gap to 6 points during the GOP gathering in Tampa.

But after the Democratic convention in Charlotte, Obama leads Romney on the economy, 50 percent to 49 percent.

Romney campaign pollster Neil Newhouse downplayed the significance of Monday’s results.

“Don’t get too worked up about the latest polling,” Newhouse said. “While some voters will feel a bit of a sugar-high from the conventions, the basic structure of the race has not changed significantly. The reality of the Obama economy will reassert itself as the ultimate downfall of the Obama presidency, and Mitt Romney will win this race.”
