No, I don't think it shows much more than some slight weaving, but it is
mildly interesting to happen mid-convention. As long as they are in
within a coupla-few points of each other this far out, I think it come
down to hand-counting ballots in many, many places. I will say that if
the Clintonistas wizz in his Wheaties during the Convention and he takes
a 8+ point hit, he'll be close to toast.
