RCP polling on this race is totally insane. As of the ened of Oct5ober and for the two polls preceeding that one (all LV), Vitter was up by strong double digits with the polls done by a Democratic Pollster PPP.
Since then three different polls have come out showing a swing towards Edwards of 34 points in just a couple of wks. Hell, even Daily Kos is skeptical and the history of these pollsters is anything but good as far as accuracy.
Detail here.

The problem is the masses made their decision c. October 24-27, and it’s bad for Vitter. Now the majority apparently will not vote at all.
