hi clo,
i don't see gallup as an especially reliable pollster these days. i didn't think their even election call made any sense. i am not going to rely on their numbers now they look more favourable.
in my view, the best stats available show the range of all polls. i wish i could find a chart that tracks side by side the results for individual polling organisations across the period. so a red line for rasmussen and a green line for pew etc.
