Washington, Sep 8 (ANI): US President Barack Obama's approval rating has bounced following the 4-day Democratic National Convention, according to a poll.
The results of a new Gallup poll show Obama now holding a 48-to-45-per-cent lead over Romney among registered voters who cast their presidential election preferences.
Obama earlier had a 47-to-46-per-cent lead over Romney, News.com.au reports.
The poll also found that Obama's approval rating had improved to 52 percent, the highest the president has enjoyed since May 2011, after the assassination of Osama bin Laden in Pakistan.
However, the poll warned that it was possible that the "upticks" were short-lived "and the race will devolve back to a parity" by next week.
"If Obama builds on and sustains his higher job approval rating and lead over Romney, it could signal a possible resetting of the presidential race" before the first debate on October 3," the polling firm said.
Opinion polls have shown Romney and Obama in a dead heat for weeks, the report said. (ANI)
