I look at Tradesports occasionally (and use it to update my Hillary-o-Meter [the successor to my pre-election Kerryometer]).
But at this point, the volume is so low that not much can be garnered therefrom.
But three things of note can be gathered from Tradesports:
1) Bill Owens is dead. Not that we didn't know this already, but Tradesports confirmed this. He used to be in third or fourth, somewhere around 13%...but has since died, going all the way down to 3-something.
2) Rudy Guiliani has no real chance. Of course, any of us could have told you that. But he used to be even with McCain at about 18...but then he dropped below 10.
3) George Allen's performance is interesting, although I'm not too sure what to make of it.
I think it's too early to declare anyone's death as of yet, though I don't see Guiliani having much of a chance.
