The trend of this poll is favourable. As you may remember the last Bush-Kerry head to head from Fox was an outlying joke (Bush, way outside MOE). Kerry is up by one among likely voters and tied among registered voters. Nader makes a tiny dent.
The main difference I see between Fox polls and others is the trends of independent voters. Elsewhere they seem to clearly be breaking for Kerry, whereas they seem far, far more conflicted at Fox. Maybe they have Hannity doing some browbeating cold calls to swing voters.
