Poll: Romney lead grows in daily tracking poll

The latest national poll shows Mitt Romney with the largest lead over President Obama this campaign based on Gallup's polling. In Gallup's Daily Tracking poll out Thursday, Romney leads the president by 7 points, with Romney obtaining 52 percent support of likely voters to Mr. Obama's 45 percent.

The results continue the latest trend shown in Gallup's polling - Romney gaining an advantage in a race that has been consistently close. Just four days ago the same poll showed Romney leading by just 2 points, which is within the margin of error.

The tracking poll obtains its average through interviews with 2,700 people over seven days. All of the respondents were asked after the first presidential debate, where, by most accounts, the president performed poorly, but only some were interviewed after the second debate where Mr. Obama had a much stronger showing.

While the latest Gallup poll shows a positive trend for Romney, a separate Gallup Poll reveals that the president's job approval rating is not suffering. Fifty percent of Americans (not necessarily likely voters) say they approve of the job the president is doing, which reflects consistent growth since the beginning of September when his job approval ratings hovered in the low- to mid-40s.
