@okie,
Rasmussen uses party ID balancing - that is to say, they poll the same number of Republicans as Dems, no matter how many people in their sample self-identify differently. So any bounce that could happen is going to be muted in their poll - and it will be the same for the Republicans next week.
Gallup allows you to self-identify and doesn't weight, so when they call 1000 people, if many more of them pick 'dem,' the numbers go up.
You can argue which is more accurate, but I think I'll go with the one that doesn't artificially limit the amount of people who can respond to a situation designed to sway voters to their side, thanks.
