President Barack Obama maintained his 3-point edge over Republican nominee Mitt Romney in Sunday's Gallup daily tracking poll, as Romney did not see a further polling surge after a consensus victory in Wednesday's presidential debate.

Romney had closed in on President Barack Obama on Saturday, turning a 5-point deficit to just 3 points. But Obama still leads Romney 49 percent to 46 percent.

Sunday's Gallup poll — which measures a seven-day rolling average — includes three days of polling after the debate. So the full effect of the debate won't be completely evident until Wednesday.

Notably, Obama's approval rating fell below 50 percent on Sunday to 48 percent, below the "safe" level for an incumbent's re-election. On Thursday, Obama's approval rating had hit its highest point in three years at 54 percent. His disapproval rating was up a point to 46 percent on Sunday.



Romney has experienced an overall surge in both national and swing-state polling since his consensus victory in Wednesday's presidential debate. In Sunday's Rasmussen poll — which included only interviews after the debate — he kept his 2-point advantage over Obama.
