Is There an Edwards Surprise Looming In Nevada?

I'm relieved that Obama and Clinton have called off the dogs (though I'd like to see the key surrogates involved whacked). But has their bickering given Edwards new life in Nevada?

For the first time since polling began in the Silver State, U.S. Sen. Barack Obama has taken a slight lead over U.S. Sen. Hillary Clinton, and former U.S. John Edwards has come within shooting distance of the two front-runners.

Of 500 likely Democratic caucus-goers surveyed, 32 percent favored Obama, 30 percent favored Clinton, and 27 percent favored Edwards.

It's up for grabs. And this is impressive (emphasis mine):

Most surprising was Edwards' standing, which jumped 15 points from the last RGJ poll in November. Edwards was second in Iowa and third in New Hampshire and has not campaigned in Nevada since those contests .
