Nevada has gone back and forth in presidential elections, enough to remain a swing state even in 2012.
President Barack Obama won Nevada in 2008 with a 12.5 percent lead over then-Republican challenger John McCain - 55.2 percent to 42.7 percent in the final results.
Latest polling data shows Obama winning the state again, however, the double-digit lead has vanished.
For the Public Policy Poll (PPP), Obama leads with 51 percent to Romney's 47 percent with a 3.9 margin of error.
The poll was conducted between Oct. 22 and Oct. 24 with 636 likely voters.
According to PPP, "Obama is already well on his way to winning Nevada based on early votes that have been cast in the week."
The PPP poll is unique, as the results have remained the same at 51 percent to 47 percent when a previous poll by PPP was taken two weeks ago, but with 584 likely voters.
PPP also noted Obama is leading with Hispanics with 69 percent to 28 percent. The president also leads with 82 percent with African Americans compared to 12 opposed. Among women, Obama is favored with 54 to 44 for Romney, and also leads 58 percent to 39 percent with young voters.
Romney' does have a narrow lead among men with 50 percent to Obama's 48 percent, this includes whites by 57 percent to 42 percent and seniors with 53 percent to Obama's 45 percent.
Public Policy Polling President Dean Debnam stated, "Barack Obama's had a persistent lead in our Nevada polling this year even if he's not likely to match his margin of victory from 2008. The Senate race looks like a toss up and is likely be decided by Obama voters who have their doubts about both of the candidates."
Nevada offer six Electoral College votes and according to Real Clear Politics is a "toss up" state, meaning it could go for either presidential candidate, but is likely to vote for Obama based on polling averages.
