(CNN) - The battle for the swing state of Nevada – which has voted for every winning president except Jimmy Carter in 1976 – is a draw in a new poll that shows Barack Obama and John McCain in a statistical tie.
McCain – a senator from neighboring Arizona – would receive 44 percent of the vote if the election were held today, according to a new Mason-Dixon poll for the Las Vegas Review-Journal. The survey finds that Obama would pull in 42 percent, a difference within the survey’s four point margin of error. Fourteen percent of likely voters remain undecided
The survey suggests that adding Clinton to the ticket could cost Obama here: 28 percent of those polled said it would make them less likely to back the Illinois senator, compared with the 19 percent who said it would make them more likely to support him. Roughly half of those polled said it would have no impact on their decision.
One out of four undecided voters said adding Clinton to the ticket would make them more likely to support Obama – but 38 percent said it would make them less likely to vote for him.
The poll of 625 likely voters was conducted June 9-11.
