Washington (CNN) -- A new national poll suggests Republican presidential nominee Mitt Romney got a bounce out of last week's first presidential debate.
According to a Pew Research Center survey released Monday afternoon, 49% of likely voters say they back Romney, with 45% supporting President Barack Obama. The survey was conducted October 4-7, the in four days after last Wednesday's first presidential debate in Denver, Colorado. Romney's four-point advantage is within the survey's sampling error.
In Pew's previous poll, conducted in mid-September, the president had a 51%-43% lead among likely voters.
Meanwhile, Gallup poll numbers released early Monday morning indicate that Obama held a 50%-45% advantage over Romney from September 30-October 2, the three days leading up to last Wednesday's presidential debate. According to the survey, Romney and Obama were deadlocked at 47% each in the three days after the debate, from October 4-6.
