Take, for instance, their large January 2010 survey aimed at proving Republicans were all kooks. They did a sample of about 2000 Republicans - a totally absurd sample size, most pollsters wouldn't in good conscience have a client pursue a survey of that size unless they had microtargeting aims and really needed a lot of subsample detail. Unless you really, really want a big sample for the smaller cells (say, you want 100 interviews from female Hispanic Republicans age 18-34) there's no reason to do a survey of that size. 1000 interviews will do for a national. Sometimes we go up to 1250 with our bigger clients who really need that level of detail on a few key subsamples. The difference in margin of error from 1000 (+/- 3.1%) and 2000 (about +/- 2%) is not a huge deal, not worth spending 2x as much on a poll.

A discussion of the poll; maybe R2K just tabulated postings on FR as the sample. When I look back at 1/09 disapproval of Obama and see it was as low as 14% in some polls, it seems that it may not have been a poor sampling strategy to use FR postings to spot a trend early on.
$oro$ has lots of $$ to waste.
