A Uni poll with far more Undecideds than every other poll of the race. Useless.
Not necessarily useless; they just didn't push undecideds/leaners as hard as some others.
Roanoke College has polled several races, from the 1994 Senate race to the 2005 governor's race, and their results were usually close to the final result (no more than a point or two off.) It looks like this is a tossup overall, judging from the many undecideds, although some of the crosstabs are hard to believe, probably from the small size of the subsamples and consequent large margins of error.
Full disclosure: I am a Roanoke College alumnus (class of 1997.)
