Must be a GOP-biased poll if it shows Baker in the lead.
Polls in non-"red states" (I guess places like AR, KY and WV are no longer purple because Presidential politics in the Obama era are all that matter?) that show Republicans are leading are considered jokes.
Indeed, Atlas seems much more objective with polls in Appalachia/Ozarks than anywhere else. I suspect some of the Dems have a hint of disdain for people in these areas and don't want to be associated with them politically, "those brain-dead, creationist, Bible-thumping rednecks." In fact, if anything, Atlas is probably a little bit biased in favor of the GOP in those areas.
