President Barack Obama has yet to shake off his poor performance at last week's first presidential debate against Republican presidential candidate Mitt Romney. Obama has struggled to maintain his lead against the GOP candidate, leading to a fluctuation in poll numbers in the days following the debate.

Over the past week alone, Gallup's Daily tracking has seen ever-changeable numbers emerge among both registered and likely voters.

Friday's Gallup Daily tracking revealed that Obama and Romney maintained their favorable ratings among registered voters, 48 percent to 46 percent respectively, in the past 24 hours. Just two days earlier, the president enjoyed a wider margin lead against Romney among registered voters at 50 percent to Romney's 45 percent.

Among likely voters, Romney scored an additional point from the previous day, bringing him to the lead at 49 percent to Obama's 47 percent. Romney again tipped the scales towards his side after tying with Obama at 48 percent on Wednesday.

President Obama's numbers among likely voters aren't the only ones taking a hit. According to the Gallup Daily tracking, his approval rating has dropped two points from the previous day to 50 percent. Obama's disapproval rating, on the other hand, jumped one point to 44 percent. 

Romney has seen a steady shift in his direction following his strong performance in the first presidential debate in Denver. However, the Republican candidate continues to suffer from lack of support among women, Latinos and black voters. Recent polls also show that Romney has yet to gain a foothold on key swing states, which could cost him the election.

The effects of Thursday night's vice presidential debate on the poll ratings for each candidate have yet to be seen. Both Vice President Joe Biden and Republican vice presidential candidate Paul Ryan performed strongly, however, some are calling Biden the winner. Biden's stronger performance may prove helpful to the Obama campaign, although vice presidential debates do not usually make a big impact among voters.

The Republican presidential candidate lagged behind Obama prior to the debates and may use the following two debates to continue his surge among both registered and likely voters.

Two remaining presidential debates between Romney and Obama are scheduled prior to the Nov. 6 election. The next presidential debate will be held on October 16 at Hofstra University in Hempstead, N.Y. and will focus on foreign and domestic policies. The last presidential debate will be held on October 22 at Lynn University in Boca Raton, Fla.
