Didn't see any postings on this, but latest NBC/WSJ poll released last night has race tied at 48% among LIKELY voters, with 1% for Nader. Among registered voters, it's 48-46-2 Bush-Kerry-Nader. 48% wrong track, 39% right track, and 33% said debates made them more likely to support Kerry, while only 17% said more likely to support Bush.
