By Jim EllisOct. 20, 2017 — A new Fox Poll (Oct. 14-16; 801 registered Alabama voters) just released earlier this week finds former state Supreme Court Chief Justice Roy Moore (R) and ex-US Attorney Doug Jones (D) tied at 42 percent in the special Alabama Senate race to be decided Dec. 12, but such a result begs further analysis.
Though the sample size appears sound from a numerical perspective, its composition causes one to doubt the final result. The actual segment cell sizes are not revealed in the analysis section, but it appears they are not wholly reflective of the Alabama electorate. Those with the greatest error factors: non-whites (+/-7 percent), liberals (+/-7 percent), moderates (+/-7 percent), and independents (+/-8.5 percent) all are strong cells for Jones. The error factors for other segments: whites (+/-4 percent), conservatives (+/-4.5 percent), and gun owners (+/-4.5 percent) are all much lower than the other tested subgroups and each of those favor Judge Moore.
While the overall error rating within the entire sample of registered voters is only listed at +/-3.5 percent, all 18 of the subgroups have corresponding rates that are much higher. This is not particularly unusual since the subgroups, by definition, are smaller than the overall sample, but the considerably larger error factor among Jones’ best groups provides us clues that the poll is skewed in the Democratic nominee’s favor.
Earlier, the Cygnal polling firm released its statewide poll (Oct. 2-5; 497 likely Alabama special election voters) finding Moore leading 49-41 percent, a survey we analyzed last week, and the ex-Judge does particularly well among those identified as most likely to vote. By contrast, the Fox sample is only of registered voters and did not screen for voting propensity. Not isolating voting likelihood is another polling factor that favors Jones’ standing.
