Bradley effect.
This is Tuesday, Wednesday, Thursday polling. Most of each days polling is completed before the nightly convention speeches.
So only Wed/Thur reflect anything based on the convention.
The Friday, Saturday, Sunday polling will reflect 3 full days AFTER the convention. We will see these tracking polls Monday.
That is why Zogby/Rasmussen are saying the bounce will not show up to early next week. Remember Obama’s bounce did not fully show up until this past Tuesday.
Anyway, the trends are good. Before the DEM convention, every poll had McCain gaining and Obama loosing. This is both national and state polls. Right before the convention, McCain was tied or ahead in most polls. And also most of these are RV polls. We have seen from recent and historical polling that republicans get an extra 2-3 points when it is narrowed to LV polls.
