This is good news for Edwards

A new poll finds a tight three-way race among Democrats and a narrow lead for Arizona Sen. John McCain among Republicans ahead of Saturday’s Nevada caucuses.

Among Democrats, the poll by Maryland-based Research 2000 for the Reno Gazette-Journal found Illinois Sen. Barack Obama at 32 percent, New York Sen. Hillary Clinton right behind with 30 percent and former North Carolina Sen. John Edwards, who many professionals and pundits have already written off, at 27 percent.
