Ed Morrissey has a look at the sampling in the latest Washington Post poll, the one that proclaims America supports a public option. Here’s what he found:
The sampling comprises 33% Democrats, as opposed to only 20% Republicans. That thirteen-point spread is two points larger than their September polling, at 32%/21%. More tellingly, it’s significantly larger than their Election Day sample, which included 35% Democrats to 26% Republicans for a gap of nine points, about a third smaller than the gap in this poll. Of course, that’s when they were more concerned about accuracy over political points of view.
Remember when I wrote that poll watchers need to remember the recent Gallup poll on party affiliation? Gallup polled 5,000 adults and found that the gap between Democrats and Republicans had closed to the smallest margin since 2005, six points, and had been reduced more than half since the beginning of the year. For the WaPo/ABC poll, though, their sample gap has increased almost 50% during that time.
Ed has a lot more. I encourage you to pop over and read it all if you haven’t already. But, wow! 13% sampling bias?! This is supposed to be news, right? Sometimes it’s hard to tell.
