ive noticed that rasmussen lags a bit in big shifts behind Gallup..its very strange.
it took almost a week after gallup to show a convention bumb.
Different methodologies. Gallup's movements are always more sudden and extreme.
That does seem to be the case. I guess the way to prove it would be to watch in 4-5 days if the numbers from Rass are comparable to the numbers gallop released today.
