McCain holds onto Nevada lead

John McCain holds onto his lead in Nevada in the latest Rasumssen survey and also gives voters better vibes than Barack Obama. The survey has the candidates at 45-42 and only 6 percent undecided. And McCain is viewed favorably by 58 percent of voters (down two points from last month) to Obama’s 47 (down five points). McCain is also doing a better job at holding onto his own party’s voters, 85 percent of Republicans supporting him to 79 percent of Democrats supporting Obama.
