OK, I wanted to post this last night, but my internet connection clunked out:
New graph thing.. update on the Gallup + Rasmussen daily tracking polls, with extra feature.
I've coloured in the sections where both polls had one candidate at a higher percentage than either poll had the other. The coloured-in part is the difference between the lower of the two polling numbers of the leading candidate and the higher of the two polling numbers of the trailing candidate.
As you can see, Hillary's only had that kind of lead once since Feb. 11 (a week after Super Tuesday), and that was just after her March 4 victories in Ohio, Rhode Island, and (sort of) Texas. The Wright affair didnt do the trick for her last month.
Obama's been in that kind of lead a couple of times, but never for long by much ... until, quite possibly, now.
