President Barack Obama and his top Republican contender Mitt Romney are about neck and neck among voters, just days before the GOP convention in Tampa, Fla.

Romney's running mate, Wisconsin Rep. Paul Ryan, has garnered a lot of attention recently, but according to a new Associated Press-GfK poll, voters remain almost split down the middle.

About 47 percent of respondents said they'd vote for President Obama, and 44 percent said they'd vote for Romney. A CNN poll put the race at 47 percent to 43 percent, respectively.

Although the president has a slight lead, most potential voters are still closely watching the race.

A separate NBC News/Wall Street Journal poll found that 62 percent of voters are still "very interested" in the race to the White House.
