Yesterday there was a 4 point shift to Kerry. Since this is only day 4 of this track there is no way to know if this was a strong Kerry sample rolling on, or a strong Bush sample rolling off.
We will know on Saturday.
Just about all the polls at the RV level are showing something in the Tied +/- MOE range, maybe a couple points edge to Bush.
With the debates and all, voter "energy" is going to be super choppy for a while, so keep you eye on the RV polls to see what is "really" happening.
The last 10 days or so will be a good time to focus back on the LV numbers.
