Obama 50%-Romney 45% in new poll

(CNN) - A new national poll released Tuesday indicates President Barack Obama with a slight edge over Republican nominee Mitt Romney, with the candidates' numbers virtually unchanged compared to their positions before the two parties' conventions.

The NBC News/ Wall Street Journal survey found Obama at 50% and Romney at 45% among likely voters. The president's five point edge is up slightly from a four point 48%-44% margin over Romney in an NBC/WSJ survey conducted in mid August, just before the Republican and Democratic conventions. Obama's five point advantage in the new poll is within the survey's sampling error, meaning the race can be seen as a tie.

The new poll was conducted entirely before Monday afternoon's release of secret recordings of remarks that Romney made at a private fund-raiser in May, where he described supporters of President Barack Obama as dependent on government. Fallout from the controversial clips has dominated coverage of the race for the White House for the past 24 hours.

The NBC News/Wall Street Journal poll is the eighth national non-partisan live operator survey to be conducted entirely after the end of both political conventions earlier this month. A CNN Poll of Polls which averages all eight surveys indicates the president at 49% and Romney at 46% among likely voters. The CNN Poll of Polls was compiled Tuesday evening, after the release of the NBC/WSJ survey. Obama's three-point advantage over Romney in the CNN Poll of Polls is approximately where the two candidates stood a month ago, before the party conventions.

Among a wider sample of registered voters, the NBC/WSJ poll indicates the president holding a 50%-44% advantage. This stands in contrast to Gallup's latest daily tracking poll of registered voters, which was also released Tuesday. According to the Gallup numbers, the president is at 47% and Romney at 46%, basically all knotted up. Obama held a seven point lead over Romney one week ago in Gallup's daily tracking poll.

According to the NBC/WSJ poll, Obama saw his high foreign policy approval ratings drop dramatically in the month since the survey was last taken. In mid-August, 54% of registered voters surveyed approved of his handling of foreign policy, while 40% disapproved. But the Tuesday ratings indicated an approval rating only 3% higher than his disapproval rating on the matter, 49% to 46%. Since the August survey was conducted, three Americans, including the ambassador to Libya, were killed in an attack on the consulate in that country, while elsewhere in the Middle East protesters have clashed with police around U.S. diplomatic posts. Romney was quick to criticize the president's handling of the situation in the Middle East.

Overall, however, Obama saw his approval rating reach 50% among registered voters for the first time since March of this year.

And registered voters also rate Obama's handling of the economy slightly better than they did last month. It now stands at 47%, up three percentage points since the August survey. .

The NBC News/Wall Street Journal survey included 900 interviews, 736 of whom were considered to be likely voters. The overall sampling error was 3.27%, and the poll was conducted by telephone between September 12 and 16.
