A new RGJ/KTVN Channel 2 poll being released today shows Nevada continues to be a true toss-up in the presidential race. In the poll of 600 likely Nevada voters, 44 percent favor U.S. Sen. Barack Obama and 43 percent favor U.S. Sen. John McCain. The results also indicate that support for Libertarian candidate, Bob Barr, expected to do well enough in Nevada to draw votes away from McCain, is slipping. He registered just 3 percent support, while independent candidate Ralph Nader is at 2 percent. Six percent of voters remain undecided.

The poll was conducted Aug. 18-20 by Research 2000 and has a 4 percent margin of error.
