A new TIME/CNN poll suggests that independent presidential candidate Ralph Nader could draw enough votes from U.S. Sen. Barack Obama (D-Ill.) to affect the outcome of the vote in Nevada.

When asked to choose between the two leading presidential candidates, registered voters gave Obama a 49 percent to 44 percent edge over U.S. Sen. John McCain (R-Ariz.).

But when offered a choice between the two major party candidates and three third-party options, Obama's five point lead turns into a 41 percent tie, with third-party candidates receiving a total of 14 percent of voter support.

Independent candidate Ralph Nader attracted 6 percent of the vote, Libertarian candidate Bob Barr received 5 percent, and Green party candidate Cynthia McKinney drew 3 percent.

It's not clear if likely voters would follow the same pattern as registered voters or if third-party voters will turn to one of the two major party candidates as November approaches, but this polls suggests there is an opportunity for McCain and a challenge for Obama in Nevada.
