"Something has methodologically gone awry when polls are swinging about this wildly," writes David Price, about presidential campaign polling. "We Americans simply don't answer our phones like we used to." Because of caller ID and cell phones, "those profiled as being most prone to answering phone surveys tend to be: (more) White, (more) older, and (more) male." The Wall Street Journal reports that how likely (as opposed to registered) voters are identified may also skew results. "Those models tend to [tilt to] a little older, a little more white, a little more affluent and a little more Republican voters," said GOP pollster Bill McInturff.
